Carbon cycle
Carbon is the fourth most abundant element in the universe and is the building block of all living things. It cycles through ecosystems in various forms and pathways. Carbon exists in the lithosphere, atmosphere, biosphere, and hydrosphere. The carbon cycle involves the exchange of carbon between living things and the air, soil, oceans, and fossil fuels through processes like photosynthesis, respiration, and decomposition.
Carbon comp
Carbon is a non-metal that forms more compounds than any other element. It can form long chains and attach to other atoms due to its unique ability to bond with itself. Pure carbon exists in two allotropes, diamond and graphite, which have identical chemical composition but different physical properties due to variations in atomic structure. Hydrocarbons are compounds of carbon and hydrogen, including saturated alkanes and unsaturated alkenes and alkynes, with alkenes containing double bonds and alkynes containing triple bonds between carbon atoms.
Oxygen presentation
Oxygen is an element with the symbol O and 8 electrons. It is essential for breathing and comes from trees. Oxygen is needed by people and animals, it is a gas, and is required for burning materials. The periodic table shows elements and their protons/electrons. The oxygen cycle connects oxygen in nature and living things.

Biogeochemical cycles C, H2O, N, and O
The document provides information about biogeochemical cycles. It discusses the water, carbon, oxygen, and nitrogen cycles. For each cycle it describes the reservoirs, how the element moves into living things, how it is returned to the Earth, and human impacts. The document emphasizes that these are continuous cycles that have always recycled these essential elements between living things and the non-living environment.
THE-CARBON-CYCLE.pptx
The carbon cycle describes the movement of carbon on Earth between the atmosphere, organisms, dead organic matter, fossil fuels, and rocks. Carbon dioxide in the atmosphere is absorbed by plants through photosynthesis and incorporated into plant tissues, then consumed by animals who incorporate it into their bodies. When plants and animals die, decomposers break down their bodies and release carbon back into the atmosphere as carbon dioxide, returning it to the cycle. Some carbon becomes trapped in fossil fuels and rocks for very long periods. Human activities like burning fossil fuels disturb this cycle by releasing large amounts of trapped carbon into the atmosphere.
The Carbon Cycle
Carbon is the fourth most abundant element and exists in compounds like CO2 that affect the planet. The carbon cycle transfers carbon between ecosystems on Earth. Humans disrupt this cycle by burning fossil fuels and releasing CO2, which causes global warming as it accumulates in the atmosphere and traps heat. Plants use CO2 in photosynthesis while animals use oxygen, and techniques like carbon sequestration aim to reduce CO2 levels.
carboncycle
The carbon cycle describes the movement of carbon between the biosphere, geosphere, hydrosphere and atmosphere. Carbon is incorporated into living things through photosynthesis and returns to the atmosphere and water through respiration, combustion and decomposition. It can also be buried deep underground over millions of years and stored as fossil fuels like coal, oil and natural gas, or as limestone, before eventually being released again through eruption or erosion. The carbon cycle is crucial for supporting life and influencing Earth's climate.

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.
Biogeochemical cycles
In Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through both the biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) components of Earth.
Greenhouse Effect, Carbon Cycle & Rising Temperatures
The document discusses the greenhouse effect, carbon cycle, and rising global temperatures. It notes that scientists have debated whether temperature rise is natural or human-caused. The 2007 IPCC report concluded global warming is very likely due to human activities like fossil fuel use that emit greenhouse gases like carbon dioxide, disrupting the natural carbon cycle. The greenhouse effect occurs as certain gases trap infrared radiation emitted from the Earth's surface, and rising CO2 levels from activities such as deforestation and burning fossil fuels are enhancing the greenhouse effect.
Carbon Food
Carbon is the basis of life and is constantly recycled through various processes. It can take many forms, including diamond and graphite, and is the fourth most abundant element in the universe. Carbon dioxide emissions contribute to global warming, so industries aim to reduce their carbon footprint by decreasing food miles, the distance food travels from farm to plate. The carbon cycle describes how carbon is exchanged between the atmosphere, ocean, living things and non-living things through various natural processes.
Carbon cycle
Carbon is a nonmetal element that is essential to life on Earth and is continuously cycled through the atmosphere, biosphere, oceans, and Earth's crust. It forms the basis of all living organisms and is a key component in regulating the planet's climate. The carbon cycle describes how carbon continuously moves between the atmosphere, living things, oceans, and Earth's crust through natural processes like respiration, photosynthesis, and volcanic eruptions. However, human activities like burning fossil fuels have increased the amount of carbon dioxide in the atmosphere, disrupting the natural carbon cycle and causing climate change.
Carbon Cycle
Carbon is one of the most important elements and is the main building block of organisms. It can be found in many everyday items and is readily available on Earth. Carbon dioxide in the air is used by plants through photosynthesis and enters animals when they eat food, then it is released back into the air through respiration. Fossil fuels are formed from decayed plants and animals over millions of years and release carbon dioxide when burned.
Carbon cycle (ANIMATED)
Carbon cycles between the atmosphere, organisms, oceans, and lithosphere. Plants absorb carbon dioxide from the air through photosynthesis, and animals obtain carbon by eating plants or other animals. When organisms die, decomposers release carbon back into the atmosphere or it becomes trapped underground in fossil fuels and other deposits. Human activities like burning fossil fuels have increased the amount of carbon dioxide in the atmosphere, contributing to global warming.

The document discusses photosynthesis and the carbon cycle. It explains that:
1) Photosynthesis uses energy from sunlight to convert carbon dioxide and water into oxygen and carbohydrates like sugar, storing the sun's energy.
2) Carbon cycles between the atmosphere, living things, oceans, soil and fossil fuels as part of the global carbon cycle. Green plants and algae absorb carbon dioxide and release oxygen through photosynthesis.
3) Photosynthesis occurs in chloroplasts and has two stages - the light dependent reactions which require sunlight, and the light independent dark reactions which can occur with or without light but are more efficient in darkness.
Biogeochemistry 303
1. Biogeochemistry is the study of the cycles of chemical elements like carbon and nitrogen through biological and geological systems over space and time. Key cycles include the carbon, nitrogen, phosphorus, and sulfur cycles.
2. These biogeochemical cycles involve the movement of elements between living and non-living components of the Earth system, including the atmosphere, lithosphere, hydrosphere, and biosphere.
3. Microbes play an important role in transforming elements between their various chemical forms and facilitating their movement between different Earth reservoirs as part of these global element cycles.
Biogiochemical cycle ppt
The biogeochemical cycle involves the movement of nutrients between living organisms and their non-living environment. This includes gaseous cycles like the carbon and nitrogen cycles, as well as sedimentary cycles involving phosphorus and sulfur. The carbon cycle is the movement of carbon between the atmosphere, organisms, oceans, soils, rocks and fossil fuels. Photosynthesis captures carbon from the air and incorporates it into organic molecules, while respiration and combustion release carbon back into the atmosphere. Human activities like burning fossil fuels and deforestation have increased carbon dioxide levels in the atmosphere.
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.
Carbon cycle
The carbon cycle describes the movement of carbon through Earth's biosphere, lithosphere, hydrosphere, and atmosphere. Carbon is exchanged between these carbon reservoirs through various biological, chemical, and geological processes. The key reservoirs and processes include:
1) Carbon is stored in the atmosphere, oceans, biosphere like plants and animals, and lithosphere like fossil fuels.
2) Photosynthesis uses carbon dioxide from the atmosphere and incorporates carbon into plants. Animals obtain carbon through eating plants or other animals.
3) Carbon is released back into the atmosphere through respiration by animals and plants and the burning of fossil fuels.
4) Carbon dioxide dissolves into oceans, lakes and rivers where it is used by marine plants
LT2.4 Carbon Cycle
The document describes the carbon cycle and key concepts about carbon. It discusses how carbon is the fundamental building block of life and is present in all living and once-living organisms. Carbon cycles between reservoirs in the atmosphere, biosphere, geosphere, hydrosphere and lithosphere through natural fluxes and processes. It moves between these spheres and reservoirs as carbon dioxide and other gases, and is exchanged between the atmosphere, plants, animals and fossils through photosynthesis, respiration, fossil fuel formation and burning.
Plant responses to the environment
Plant responses to environmental stimuli are called tropisms. Tropisms describe the growth or turning movement of a plant in response to external factors and can be positive, towards the stimulus, or negative, away from the stimulus. The main tropisms include phototropism, where plants grow towards light; geotropism, where plants grow towards or against gravity; thigmotropism, where plants respond to physical touch; and hydrotropism, where plants sense and grow towards sources of water.
Protista Kingdom
Protists are eukaryotic organisms that are mostly single-celled and can reproduce both sexually and asexually. They are decomposers and consumers. There are three main groups of protists: fungus-like protists, plant-like protists called algae, and animal-like protists called protozoa. Protozoa move using flagella, cilia, pseudopods, or they cannot move if they are parasitic. Some disease-causing protists are Giardia, which causes diarrhea, and Plasmodium, which is carried by mosquitoes and causes malaria.

Seed plants characteristics
Seed plants have three main characteristics: 1) they have vascular tissue that transports nutrients and water throughout the plant, 2) they reproduce using seeds, and 3) they have a complex life cycle involving sporophytes and gametophytes. Seeds contain an embryo, stored food, and a protective seed coat. The embryo develops into a new plant, the stored food nourishes the embryo's growth, and the seed coat protects these parts. Leaves capture sunlight for photosynthesis, stems transport nutrients and provide structure/support, and roots anchor the plant and absorb water and nutrients.
Plant kingdom characteristis
Plants share three key characteristics: they are eukaryotic, multicellular, and autotrophic, obtaining their energy through photosynthesis. They have five adaptations for living on land: obtaining water and minerals from soil through root systems; retaining water through a cuticle layer; transporting materials through vascular tissue and cells; supporting their bodies through leaves exposed to sunlight and vascular tissue; and most engaging in sexual reproduction through fertilization. Plants have a complex life cycle with two alternating stages - the sporophyte stage produces spores, while the gametophyte stage produces sex cells that fuse to form a zygote and restart the cycle.
Plant divisions mosses and ferns
The document summarizes the characteristics and life cycles of nonvascular and seedless vascular plants. It describes two divisions of plants - nonvascular plants like moss that lack roots, stems, and leaves, and vascular plants that have transport tissues. Moss and liverworts are examples of nonvascular plants that reproduce via alternation of generations between sporophyte and gametophyte stages. Ferns are an example of seedless vascular plants that have true stems, roots, and leaves called fronds. Their life cycle also involves alternation between sporophyte and gametophyte stages. Ferns and other seedless plants were important in forming peat bogs and peat, which was used as fuel.
Plant divisions gymnosperms and angiosperms
This document summarizes the key characteristics and divisions of vascular seed plants. It describes the two main groups, gymnosperms and angiosperms. Gymnosperms produce naked seeds on cone scales, lack flowers, and have needle-like or scale-like leaves. They are divided into four groups including conifers. Angiosperms enclose seeds in an ovary that develops into a fruit. They are characterized by flowers and are divided into monocots and dicots.
Plant characteristics
Plant characteristics include being made of cells with DNA, cell walls, and chloroplasts. They are multicellular producers that make their own food through photosynthesis. There are two main types of plants: nonvascular and vascular. Nonvascular plants like mosses and liverworts do not have roots, stems or leaves, lack vascular tissue, and reproduce through spores. Vascular plants contain vascular tissue to transport food and water, and some contain seeds while others reproduce through spores.
Parts of a flower
The document describes the main parts of a flower, including the petals that attract insects, the pistil made up of the stigma, style and ovary that receives and protects pollen and ovules, the stamens that contain pollen in anthers, and the sepals that protect the developing flower bud. It explains the functions of each part in plant reproduction, such as the style raising the stigma to reduce self-pollination and the ovary protecting the ovule to later become the fruit after fertilization.

It provides details on the functions of each part in plant reproduction and fertilization.
Fungi Kingdom
Fungi are single or multi-cellular organisms that are eukaryotic, have cell walls, and reproduce via spores. There are several types of fungi including mushrooms, shelf fungi, molds, and yeasts. Fungi can act as decomposers to break down dead organic matter and recycle nutrients or cause harm by destroying crops, spoiling food, and causing diseases in plants and animals.
5.00 History of time
Fossils, Molds, Casts provides information about fossils and the geological time scale. It aims to describe how fossils record Earth's history and evidence of evolution. Key points include that fossils are preserved plants and animals, the law of superposition establishes layer age relationships, and absolute dating determines fossil ages in years using radioisotope methods. The geological time scale is a calendar used by scientists to outline Earth and life history, broken into eras like the Paleozoic, Mesozoic, and Cenozoic. Mass extinctions have occurred throughout Earth's history.
5.03 Evolution
Phones and personal music devices have changed significantly over time. The document discusses key concepts from evolution including species, adaptations, Charles Darwin, and his observations of finches in the Galapagos Islands. It notes that adaptations arise due to DNA mutations and are not chosen by organisms, helping them survive and reproduce based on their environment.

5.00 Animal adaptations
1. An adaptation is anything that helps an organism survive in its environment. Adaptations develop over many generations through evolution, not during an individual animal's lifetime.
2. There are several types of adaptations including structural adaptations like physical features, behavioral adaptations like ways animals act, camouflage to blend into surroundings, mimicry where animals resemble other dangerous species, and warning coloration where bright colors signal being poisonous.
3. Examples of adaptations include a bird's beak shape, a rabbit freezing when scared, a snake's camouflage patterns, a monarch butterfly mimicking the viceroy, and poisonous coral snakes having distinctive black-yellow-red banding.
5.00 the earth’s history
The document discusses theories about the Earth's history, including relative dating which estimates the age of fossils based on their position in layers, absolute dating which determines age based on unstable atoms, and the geologic time scale which outlines life on Earth. It also defines key terms like extinct species, Pangaea as the land once connected into one continent, and plate tectonics as the theory of crustal plates moving over time.
5.03 natural selection
This document provides notes on natural selection. It begins by stating the objective is to explain how natural selection works. It then outlines the four main steps of natural selection: 1) overproduction where each species produces more offspring than will survive, 2) genetic variation between individuals provides different traits that help or hurt survival, 3) struggle to survive and competition for limited resources means only some individuals survive to adulthood, 4) successful reproduction where the individuals best adapted to the environment are more likely to survive and pass on their genes, leading to evolution over long periods of time. Examples of adaptations like camouflage and fast swimming are provided. The document asks questions to check understanding of natural vs artificial selection and factors controlling natural selection.
5.00 Animal phylum
1. Animals are multicellular organisms that obtain energy by consuming other organisms. They are classified as vertebrates, which have backbones, or invertebrates, which do not.
2. The document describes several animal phyla - Cnidaria, which includes jellyfish and coral, have stinging cells; Annelida includes segmented worms; Mollusks have a muscular foot and shells; Echinodermata are spiny with radial symmetry and tube feet; Arthropoda are the most successful and include insects, spiders, and crustaceans; and Chordata are backboned and include fish, amphibians, reptiles, birds, and mammals.

5.00 dichotomous keys 2010
Dichotomous keys are tools used by scientists to classify organisms. They are arranged in steps with two descriptive statements at each step, where one statement leads to the next step or the name of the organism. Dichotomous keys help scientists methodically sort and identify organisms based on observable characteristics.
5.07 classification kingdoms
This document outlines the six kingdoms of classification: Archaebacteria, Eubacteria, Protista, Fungi, Plant, and Animal. It provides details on the key characteristics of each kingdom, including whether they are prokaryotic or eukaryotic, unicellular or multicellular, producers or consumers, and how they reproduce. Examples are given for each kingdom, such as archaebacteria living in extreme environments, eubacteria including decomposer bacteria, protista including algae and amoebas, fungi being decomposers like mushrooms and mold, plants being producers that undergo photosynthesis, and animals being able to move and being consumers.
