The document summarizes the oxygen and carbon cycles. It explains that oxygen is essential for life on Earth and makes up a large percentage of the human body and atmosphere. It then describes the oxygen cycle, where plants produce oxygen through photosynthesis, using carbon dioxide, sunlight and water, and animals release carbon dioxide when breathing. When plants and animals die they decompose and release carbon dioxide back into the atmosphere. The carbon cycle is also summarized, where plants take in carbon dioxide during photosynthesis and either use it to build tissues or release it, and carbon is passed between plants, herbivores and other organisms.

Oxygen cycle
Oxygen cycles through the biosphere, atmosphere, hydrosphere, and lithosphere. Plants produce oxygen through photosynthesis, using carbon dioxide, water and sunlight to produce sugars and release oxygen into the atmosphere. Animals and other organisms use oxygen for respiration, breaking down sugars and food and releasing carbon dioxide and water. The carbon dioxide is then used by plants in photosynthesis, continuing the cycle.

4. the oxygen cycle
Oxygen is a colorless, odorless gas that is less dense than air and a poor conductor of heat and electricity. It cycles between the atmosphere, plants, animals, and oceans through photosynthesis and respiration. Photosynthesis produces oxygen as a byproduct in plants, which is then used by animals through respiration and releases carbon dioxide back into the atmosphere. Oxygen levels on Earth have increased over time as photosynthesis evolved and continues to be balanced between the atmosphere and bodies of water.
OXYGEN CYCLE
Ali Hyder presented on the oxygen cycle to the Microbiology and Biotechnology department. The presentation covered definitions of key terms like biogeochemical cycles and oxygen. It explained that oxygen is produced primarily through photosynthesis by plants and some through interactions with sunlight and water vapor. Oxygen gets used up through respiration by animals and organisms, decomposition of dead matter, rusting of metals, and combustion. The oxygen cycle occurs as plants produce oxygen through photosynthesis during the day, which is then used by organisms for respiration and releases carbon dioxide, which plants then use again at night through photosynthesis, repeating the cycle.
Oxygen cycle
The oxygen cycle describes the movement of oxygen gas through the atmosphere, biosphere, hydrosphere, and lithosphere. Oxygen is produced through photosynthesis by plants and released into the atmosphere. Aerobic organisms like animals then use this oxygen for respiration, exhaling carbon dioxide back into the atmosphere. Oxygen dissolves in water and is used by aquatic life in the hydrosphere. The lithosphere contains oxygen in minerals like silica and oxides. This cycle is important for supporting aerobic respiration in humans, animals, and aquatic organisms as well as for decomposition.
Carbon-Oxygen Cycle
The carbon-oxygen cycle involves four main processes: photosynthesis, respiration, combustion, and decomposition. During photosynthesis, plants take in carbon dioxide and water and release oxygen and energy from sunlight. Respiration is the opposite process, where animals and plants take in oxygen and release carbon dioxide and energy. Combustion releases carbon dioxide into the atmosphere through natural events like volcanoes and the burning of fossil fuels. Decomposition returns carbon and other elements back to the soil and air when organisms die.

Burning fossil fuels has increased the amount of carbon dioxide in the atmosphere, contributing to global climate change. The carbon cycle is essential for life and affects Earth's climate.
The Oxygen Cycle
Oxygen makes up 21% of the atmosphere and is used by all living things through respiration and photosynthesis. During respiration, glucose and oxygen are used to produce energy, carbon dioxide, and water. In photosynthesis, plants use carbon dioxide, water, and sunlight to produce oxygen and glucose. This cycle of oxygen production and consumption between organisms through respiration and photosynthesis is essential for life.
Carbon cycle
Carbon is an element that is the basic building block of living things like humans, animals and plants. It is also found in rocks, oceans, and greenhouse gases in the atmosphere. The carbon cycle is the movement of carbon between the earth and atmosphere, as carbon is recycled through plants, animals, and the environment over time. Humans impact the carbon cycle through burning fossil fuels, which releases stored carbon and increases carbon dioxide in the atmosphere, contributing to global warming. To reduce this impact, people can burn less fossil fuels and promote plant growth that absorbs carbon dioxide.
Ozone Layer and Chemicals
This presentation is about Ozone Layer and chemicals known to cause its depletion.
It also covers information about Ozone Hole and Correlation between Ozone depletion and skin diseases due to Ultra Violet light.It also contains no. of ways to limit ozone deterioration.
Carbon cycle
Carbon cycles between the earth and atmosphere in a repeating process. Plants absorb carbon dioxide from the air through photosynthesis, and animals release carbon back to the air when they exhale or when dead plants and animals decompose. Some carbon becomes trapped underground in deposits like oil and coal, and is slowly released back into the atmosphere over long periods of time. Human activities like burning fossil fuels have increased the amount of carbon dioxide in the atmosphere, intensifying the greenhouse effect and global warming.
Oxygen cycle pres 1
Oxygen is a tasteless and odorless gas that comprises 22% of the air and supports combustion. It is essential for photosynthesis, which converts carbon dioxide and water into oxygen and carbohydrates like sugars to chemically store energy from sunlight in plants, algae and cyanobacteria. The oxygen cycle describes its movement through three main reservoirs: the atmosphere, biosphere, and lithosphere. Failure of the oxygen cycle in the hydrosphere can create hypoxic zones with low oxygen levels harmful to marine life.

Presentation on photochemical smog (1) final.pptx
Photochemical smog is formed when sunlight reacts with nitrogen oxides and volatile organic compounds in the atmosphere. It causes a brown haze and health issues. Acid rain is caused by emissions from industries and vehicles reacting with water, moisture, and oxygen in the air to form acids. It harms plants and ecosystems. Chlorofluorocarbons are man-made gases used in aerosols and refrigerants that contribute to global warming and deplete the ozone layer, which protects the Earth from ultraviolet radiation.
The Atmosphere
The atmosphere is composed of four main layers: the troposphere, stratosphere, mesosphere, and thermosphere. The troposphere contains around 75% of the atmosphere's mass and is where weather occurs. The stratosphere contains the ozone layer which protects the Earth from UV radiation. The thermosphere is the hottest layer due to absorption of solar radiation.
Carbon cycle
Carbon is an essential element that cycles between the atmosphere, ocean, organisms, and geologic reservoirs as part of the carbon cycle. Photosynthesis incorporates carbon from the air and water into organic compounds, while respiration and decomposition release it back. Fossil fuels like coal and oil were formed from ancient plant and algae remains over millions of years. Burning fossil fuels returns carbon to the air, and limestone erosion also adds carbon back to the cycle through weathering. The carbon cycle continuously moves carbon between the biosphere and geosphere.
Water Distribution on Earth
The document discusses the distribution of water on Earth. It notes that:
- 71% of the Earth's surface is covered in water, but 97% of that water is salty ocean water, leaving only 3% as freshwater.
- The major stores of freshwater are glaciers/ice (2.15%), groundwater (0.61%), and freshwater lakes (0.009%). Smaller amounts are found in the atmosphere, inland seas, soil moisture, and rivers.
- Water is distributed through the hydrologic cycle and, while it changes forms, the amount of water on Earth remains fairly constant over time as it is recycled.
Ozone depletion
The ozone layer is a layer in the stratosphere between 20-30 km above the Earth's surface that contains 90% of the atmosphere's ozone. Ozone is formed through the Chapman cycle where oxygen is converted to ozone via ultraviolet radiation. Ozone depletion occurs when gases like CFCs and halons react with ozone due to UV radiation, forming chlorine atoms that can destroy 100,000 ozone molecules each. This causes thinning of the ozone layer, known as the ozone hole over Antarctica. Ozone depletion leads to increased UV radiation reaching the Earth, harming humans, animals, plants and contributing to global warming. International agreements like the Montreal Protocol aim to phase out ozone depleting
carbon cycle
Carbon has an important role in environment so its important to know about the carbon cycle.Here is the brief description of carbon cycle.
Ozone
The document discusses the ozone layer, its importance in shielding the Earth from UV radiation, and the threats to it. It notes that ozone is found mainly in the stratosphere, where it forms the ozone layer between 6-30 miles above the surface. The ozone layer absorbs most of the sun's UV rays and plays a key role in atmospheric temperature. However, chlorofluorocarbons and other ozone-depleting substances have damaged the ozone layer, leading to the Antarctic ozone hole. This depletion increases UV levels and can harm both human health and the environment. International agreements like the Montreal Protocol have sought to phase out ozone-harming chemicals and find alternatives.
Ozone layer depletion ppt
The ozone layer absorbs most UV radiation from the sun. It contains high concentrations of ozone and is mainly located in the lower stratosphere. Chlorofluorocarbons (CFCs) and other halogenated compounds released by human activities are the primary cause of ozone depletion by destroying ozone molecules. This has led to a 4% decline in ozone per decade and the formation of an ozone hole over Antarctica. Increased UV radiation due to ozone depletion poses risks to human health, animals, and crop production. The Montreal Protocol was adopted in 1987 to phase out ozone depleting substances to protect the ozone layer.
Carbon cycle
Carbon is essential for life and is continuously cycled through Earth's biosphere, lithosphere, hydrosphere and atmosphere. The carbon cycle involves the exchange of carbon reservoirs between the atmosphere, ocean, biomass and fossil fuels. Photosynthesis absorbs carbon from the atmosphere which enters the biosphere, and respiration and decomposition release it back into the atmosphere. Human activity such as burning fossil fuels has increased carbon dioxide levels in the atmosphere, disrupting the natural carbon cycle balance.
Biogeochemical cycles
The document summarizes several major biogeochemical cycles - carbon, nitrogen, phosphorus, and sulfur. It describes the reservoirs, fluxes, and transformations involved in each cycle, which are driven by biological and geological processes. Microbial activity plays an important role in facilitating exchanges between different reservoirs like the atmosphere, biosphere, hydrosphere and lithosphere. The carbon, nitrogen and sulfur cycles involve gaseous forms that are exchanged between air and oceans/land. Phosphorus lacks a gaseous phase and its cycle is more sedimentary in nature.
Nitrogen cycle
The document discusses the nitrogen cycle. It describes how nitrogen exists in the atmosphere but is converted by bacteria and algae into forms that can be used by plants and animals through biological fixation. Lightning and industrial processes also fix nitrogen. Plants take up nitrogen from the soil and animals get nitrogen from eating plants. Nitrogen is returned to the soil through animal waste or decay. Bacteria then convert nitrogen back into forms that can re-enter the atmosphere, completing the cycle. The nitrogen cycle is essential for providing the nutrient needs of all living things.
Carbon cycle
The carbon cycle describes the movement of carbon through the biosphere, geosphere, hydrosphere and atmosphere. Carbon is exchanged through processes like photosynthesis, respiration, and the weathering of rocks. Recently, the carbon cycle has become imbalanced due to human activities like burning fossil fuels and deforestation, which emit carbon dioxide into the atmosphere faster than natural processes can reabsorb it. The excess carbon dioxide is causing global warming and has negative effects on plants, humans and the climate.

Nitrogen cycle
The nitrogen cycle is a natural process in which atmospheric nitrogen enters the soil and becomes part of living organisms. It is essential to living things and plays an important role in ecosystems. The steps of the nitrogen cycle are nitrogen fixation, nitrogen assimilation, ammonification, nitrification, and denitrification. Human activities like cultivation, harvesting, and fossil fuel use can disrupt the nitrogen cycle and cause over-supply of nitrogen in the environment, leading to issues like soil acidification and increased greenhouse gases.
Nitrogen Powerpoint
Nitrogen is the fifth most abundant element in the universe and makes up 80% of the Earth's atmosphere. It is a colorless and odorless gas that does not burn and is slightly soluble. Nitrogen is essential for life and is a component of proteins, amino acids, and fertilizers. It is widely used to make ammonia and in food freezing and rocket fuel production.
Ppt Nutrient Cycles
The carbon cycle involves carbon dioxide being absorbed by plants through photosynthesis and converted into sugars, which are then consumed by animals through respiration and released again as carbon dioxide, completing the cycle. The nitrogen cycle transforms nitrogen between its gas and solid forms via nitrogen-

The Carbon Cycle by Tangstar Science
1) Carbon cycles through both living and non-living components of the environment through various processes.
2) Photosynthesis removes carbon dioxide from the atmosphere and cellular respiration releases it back.
3) Carbon is also stored long-term in fossil fuels through the fossilization of ancient plants and animals, and released through their combustion.
Respir8n 6
1) The partial pressure of each gas in a mixture is directly proportional to its percentage. Gases dissolve in liquids according to their partial pressures based on Henry's law.
2) Respiratory membranes are only 0.5-1 μm thick, allowing for efficient gas exchange across their large total surface area of about 60 m2.
3) Factors that maximize gas exchange include increasing the partial pressure difference of gases, maximizing membrane surface area, and minimizing membrane thickness.
Carbon-Oxygen Cycle
The document discusses the carbon/oxygen cycle which involves four main processes:
1. Photosynthesis where plants take in carbon dioxide and water to release oxygen and sugar using energy from the sun.
2. Respiration where animals take in oxygen and sugars to release carbon dioxide, water, and energy.
3. Combustion which is the burning of fossil fuels like coal, gas, and oil, releasing carbon dioxide. This over-contribution of carbon dioxide is accelerating global warming.
4. Decomposition where dead plants and animals are broken down by insects, fungi and bacteria, returning carbon and other elements to the soil and air.
Nitrogen Cycle
1. Nitrogen-fixing bacteria convert nitrogen gas from the air into nitrates that can be used by plants and animals.
2. Plants take up nitrates and use them to produce proteins. Animals obtain protein by eating plants or other animals.
3. After death or waste excretion, decomposer bacteria break down organic matter into nitrates, completing the cycle.

Nitrogen Cycle Powerpoint
The document summarizes the nitrogen cycle, which is a process by which nitrogen is converted between its various chemical forms and circulated among air, land, water, and living organisms. Nitrogen is essential for all life and comprises 70-71% of the atmosphere. It enters organisms through eating, drinking, and breathing and is converted to forms such as ammonium, nitrates, and urea that can be used by plants and animals. The nitrogen cycle is linked to the water cycle as nitrogen is absorbed by plants from the soil and returns to the atmosphere.
Nitrogen cycle
1. The nitrogen cycle describes how nitrogen is converted between its various forms and moves between the atmosphere, soil, plants, and animals.
2. Atmospheric nitrogen is converted to ammonia or nitrates through nitrogen fixation, which allows plants and animals to use it.
3. Nitrification and ammonification convert ammonia into other nitrogen forms that plants can use, and denitrification returns nitrogen to the atmosphere, completing the cycle.
Nitrogen fixation
Carbon is the major constituent element in plants after water. It is found in important biomolecules like chlorophyll, cytochromes, alkaloids, and many vitamins. Nitrogen plays an important role in plant metabolism, growth, reproduction and heredity. Plants cannot utilize atmospheric nitrogen directly and require nitrogen-fixing bacteria to convert it into bioavailable forms like nitrates, nitrites and ammonia. Nitrogen fixation can occur through both biological and non-biological means, with biological nitrogen fixation involving symbiotic associations between plants and nitrogen-fixing microorganisms like Rhizobium bacteria.

Carbon and Oxygen Cycle PPT for Class 9 children
The carbon and oxygen cycles are interconnected processes that regulate the flow of carbon and oxygen between the atmosphere, oceans, soil and living organisms. The carbon cycle involves photosynthesis, respiration, decomposition and combustion, circulating carbon through ecosystems. Photosynthesis uses carbon dioxide and sunlight to produce oxygen and organic compounds. Respiration and decomposition release carbon dioxide and power cellular functions. Combustion releases carbon dioxide through burning of fossil fuels. The oxygen cycle ensures a steady oxygen supply through photosynthesis and atmospheric exchange, while respiration uses oxygen for energy. Human impacts like deforestation and fossil fuel use disrupt these natural cycles.
Project
The carbon-oxygen cycle describes the exchange of carbon and oxygen between living things and the environment. During photosynthesis, plants take in carbon dioxide from the air and release oxygen, while cellular respiration in animals and plants involves taking in oxygen and releasing carbon dioxide. Decomposers further break down dead organisms, releasing carbon dioxide back into the air. This cycle is essential for supporting life on Earth.
OXYGEN CYCLE.pptx
The document discusses the oxygen cycle, which involves oxygen moving between the atmosphere, lithosphere, and biosphere. During photosynthesis, plants release oxygen into the atmosphere. Aerobic organisms then use this oxygen for respiration and release carbon dioxide. The three main stages are: 1) plants release oxygen during photosynthesis, 2) aerobic organisms use oxygen during respiration, and 3) animals exhale carbon dioxide used by plants. The oxygen cycle helps maintain oxygen levels in the air, water, and living things.
Carbon cycle
The carbon cycle describes how carbon is exchanged between the atmosphere, organisms, oceans, and the Earth's crust. Carbon dioxide enters the atmosphere through volcanic emissions and respiration. Plants and algae absorb carbon dioxide through photosynthesis and incorporate carbon into organic molecules. Animals consume these organic molecules and release carbon dioxide during respiration. Decomposers break down dead organic matter, releasing carbon back into the atmosphere and oceans. Human activities like burning fossil fuels have increased atmospheric carbon dioxide levels, altering the natural carbon cycle.

2) Water contributing by allowing oxygen to enter and dissolve from the air, creating a high surface area for transfer.
3) Living organisms like humans and animals contributing through respiration, breathing in oxygen and out carbon dioxide, linking back to plants through photosynthesis.
Ppt on Biogeochemical Cycle USacademy.in
The document provides information about various biological cycles including nitrogen, oxygen, and carbon cycles. It discusses:
1) The stages of the nitrogen cycle including nitrogen fixation, nitrification, assimilation, ammonification, and denitrification. Nitrogen is transformed between different reservoirs and made usable by organisms.
2) The oxygen cycle moves oxygen between the atmosphere, biosphere, and lithosphere. Oxygen is released during photosynthesis and used in respiration and other processes.
3) The carbon cycle involves the movement of carbon between the atmosphere, geosphere, biosphere, hydrosphere, and pedosphere in elemental and combined states. Carbon is recycled through different carbon reservoirs on Earth.
Cycling of matter
Matter cycles between living and nonliving components in ecosystems through biogeochemical cycles. Key cycles discussed include water, carbon, oxygen, and nitrogen. Matter is recycled through producers, consumers, and decomposers. Toxins can accumulate and concentrate in organisms at higher trophic levels since they are not biodegradable and biomass decreases at each level. This was seen with DDT accumulation in birds, interfering with egg shell formation and reproduction.
Cycle of Matter and Cycle of Change
This document discusses cycles of matter and ecological succession. It describes the oxygen, carbon, and water cycles, explaining how photosynthesis and respiration drive the exchange of gases. It also outlines the process of primary and secondary ecological succession, where pioneer species establish communities that over time develop into a climax ecosystem. Human impacts like burning fossil fuels and deforestation disrupt these natural cycles.
Carbon_Cycle.ppt
The carbon cycle describes how carbon is exchanged between the atmosphere, biosphere, geosphere, and hydrosphere via various processes. Carbon is recycled continuously through photosynthesis, respiration, decomposition, combustion, and other processes. When plants and animals die, carbon is released back into the atmosphere through decomposition. However, human burning of fossil fuels is rapidly releasing long-stored carbon and increasing atmospheric carbon dioxide levels, causing global warming.
Carbon_Cycle.ppt
The carbon cycle describes how carbon is exchanged between the atmosphere, biosphere, geosphere, and hydrosphere via various processes. Carbon is recycled continuously through photosynthesis, respiration, decomposition, combustion, and other processes. When plants and animals die, carbon is returned to the atmosphere or deposited underground. Burning fossil fuels unbalances the carbon cycle by releasing stored carbon too quickly, increasing atmospheric carbon dioxide and global warming.

Carbon-oxygen cycle
The carbon dioxide-oxygen cycle is the process by which carbon dioxide and oxygen move through the natural environment via photosynthesis, respiration, combustion, and decomposition. During photosynthesis, plants absorb carbon dioxide and convert it to sugar using sunlight, releasing oxygen. Animals breathe in oxygen and release carbon dioxide during respiration. Combustion and decomposition also release carbon dioxide back into the air, completing the cycle.
biogeochemical_cycles_chapter_5_1.ppt
Biogeochemical cycles describe the movement of elements and molecules through biotic and abiotic components of ecosystems. Key cycles include carbon, nitrogen, oxygen, phosphorus, and sulfur. In these cycles, matter is transferred between living organisms, non-living matter like soil and water, and long-term stores like fossil fuels and sedimentary rocks. The recycling of nutrients through biogeochemical cycles is essential for sustaining life on Earth.
Biogeochemical cycles chapter_5
Biogeochemical cycles describe the movement of elements and molecules through biotic and abiotic components of ecosystems. Major cycles include carbon, nitrogen, oxygen, phosphorus, and sulfur, which circulate crucial nutrients through the biosphere, hydrosphere, atmosphere, and lithosphere. These recycling processes are essential to sustaining life as they maintain the chemical conditions necessary for organisms to survive.
the importance of the carbon cycle
The carbon cycle is a complex series of processes through which carbon atoms are recycled and reused. Plants absorb carbon dioxide from the atmosphere through photosynthesis and animals release carbon dioxide through respiration, allowing carbon to be reused. The carbon cycle is essential for producing food and renewable resources through photosynthesis and decomposition, and serves as the earth's waste disposal system through decomposition. It also affects the climate as carbon dioxide in the atmosphere causes warming.
Environmental Science - Biogeochemical Cycle
Biogeochemical cycles help explain how elements are recycled through ecosystems. The most common cycles include water, carbon, nitrogen, sulfur, and phosphorus. Biogeochemical cycles consist of chemical, geological, and biological processes that circulate elements between living organisms and their inorganic environment. They maintain the flow of energy and matter through ecosystems and allow for the transformation and storage of elements. Examples provided include the water cycle, carbon cycle, and nitrogen cycle.
Nutrient cycles presentation
Three key nutrient cycles - water, carbon, and nitrogen - allow organisms to obtain needed nutrients. The water cycle is driven by the sun and involves evaporation from bodies of water and transpiration from plants, condensation in the atmosphere, and precipitation back to the ground. The carbon cycle moves carbon between living things and the atmosphere, with photosynthesis fixing carbon and respiration releasing it. Nitrogen gas makes up 80% of the atmosphere but is not directly usable, so bacteria play a crucial role in nitrogen fixation, making nitrogen bioavailable to plants through processes like nitrification and ammonification.
05 ecological niches and cycles
1) The document describes ecological niches and the nitrogen and carbon cycles.
2) An ecological niche includes what a species feeds on, what feeds on it, and how it behaves in its habitat. The niche of black bears is given as an example.
3) The nitrogen and carbon cycles describe how nitrogen and carbon move between the atmosphere, living things, and the lithosphere through natural processes like photosynthesis, cellular respiration, nitrogen fixation, and weathering.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Oxygen cycle and Carbon cycle
- 2. Facts about Oxygen -is an important element to life on Earth. -It is the most common element of the human body. It makes up about 65% of the mass of the human body. -also makes up about 30% of the Earth and 20% of the atmosphere.
- 3. Oxygen Cycle
- 4. What is Oxygen Cycle? • In the simple example of the oxygen cycle shown, you can see how oxygen is used and cycled by plants and animals. Plants are the main creators of oxygen in the atmosphere through the process of photosynthesis. Here the tree uses sunlight and carbon dioxide to produce energy and releases oxygen. The giraffe breathes in the oxygen and then breathes out carbon dioxide. The plant can then use this carbon dioxide and the cycle is complete.
- 5. Processes that USE Oxygen -Breathing -Decomposing -Combustion -Rusting The scientific name for breathing is respiration. All animals and plants use up oxygen when they breathe. They breathe in oxygen and breathe out carbon dioxide. When plants and animals die, they decompose. This process uses up oxygen and releases carbon dioxide. This is also called oxidation. When things rust they use up oxygen. There are three things needed for fire: oxygen, fuel, and heat. Without oxygen you can't have a fire. When things burn, they use up oxygen and replace it with carbon dioxide.
- 6. Plants What produces Oxygen? Sunlight Plants create the majority of the oxygen we breathe through a process called photosynthesis. In this process plants use carbon dioxide, sunlight, and water to create energy. In the process they also create oxygen which they release into the air. Some oxygen is produced when sunlight reacts with water vapor in the atmosphere.
- 7. Fun Facts! • Even though fish breathe under water they still breathe oxygen. Their gills extract the oxygen from the water. • There is a lot of oxygen stored up in the oxide minerals of the Earth's crust. However, this oxygen isn't available for us to breathe.
- 9. What is Carbon Cycle? • Carbon Cycle (ecology), in ecology, the cycle of carbon usage by which energy flows through Earth’s ecosystem. • The basic cycle begins when photosynthesizing plants use carbon dioxide (CO2) found in the atmosphere or dissolved in water. Some of this carbon is incorporated in plant tissue as carbohydrates, fats, and protein; the rest is returned to the atmosphere or water primarily by aerobic respiration. • Carbon is thus passed on to herbivores that eat the plants
