This document discusses biogeochemical cycles, specifically the carbon, nitrogen, and phosphorus cycles. It notes that the carbon cycle involves both gaseous (CO2, CH4) and non-gaseous forms. The nitrogen cycle moves between the atmosphere as N2 gas, into the soil through nitrogen fixation by bacteria, into plants, then back through decay. Phosphorus differs in that it has no gaseous stage and is stored in rocks and soil organic matter, becoming available to plants through microbial conversion to phosphates.

Biogeocycles
The document discusses biogeochemical cycles, specifically gaseous cycles. It provides details on the nitrogen cycle, including the steps of nitrogen fixation, nitrate assimilation, ammonification, nitrification, denitrification, and sedimentation. It also briefly summarizes the carbon cycle, noting it is a perfect gaseous cycle as carbon transfers and transformations occur quickly between the atmosphere and organisms through photosynthesis, respiration, decomposition and other processes.
Nitrogen fixation,
Nitrogen fixation is a process where nitrogen in the atmosphere is converted into forms usable by living organisms like ammonia. It is carried out by nitrogen-fixing bacteria in soil and symbiotically in legumes. The nitrogen cycle describes how nitrogen circulates between ecosystems through biological and physical processes like fixation, ammonification, nitrification, and denitrification. The carbon cycle similarly exchanges carbon between the biosphere, atmosphere, hydrosphere, geosphere, and pedosphere through chemical, geological, and biological processes. It was key to making Earth habitable but human activities have significantly impacted the global carbon and nitrogen cycles.
Biogeochemical Cycles/Environmental Science
1. Biogeochemical cycles move nutrients like carbon, nitrogen, water, and phosphorus through air, water, soil, rock and living organisms.
2. Humans impact biogeochemical cycles by withdrawing freshwater, polluting water sources, clearing vegetation, burning fossil fuels, using inorganic fertilizers, and contributing to climate change which alters natural cycling processes.
3. The carbon, water, nitrogen, and phosphorus cycles are described in detail, outlining the reservoirs, assimilation, and release steps involved in naturally circulating those elements through the environment.

This document discusses the sulfur cycle. It begins by defining sulfur as a yellow, odorless mineral that is essential for living organisms. It then describes the three natural ways sulfur enters the atmosphere: from sea spray, volcanic activity, and bacterial respiration. It explains that sulfur is released as hydrogen sulfide and oxidized to sulfate before returning to earth. The document also outlines the steps of the sulfur cycle and the effects of sulfur on nature and the human impact through fossil fuel combustion.
NITROGEN CYCLE INRELATION TO GEOLOGY
This document provides an overview of the nitrogen cycle presented by a group of students from Gauhati University. It begins with an introduction to geochemical cycles and defines nitrogen. It then describes the major processes in the nitrogen cycle, including nitrogen fixation, mineralization, nitrification, and denitrification. It discusses the role of microorganisms and how human activities like fertilizer use and fossil fuel combustion have impacted the global nitrogen cycle. Reservoirs of nitrogen in the terrestrial environment and crust are also examined.
Biogeocycles
This document discusses several biogeochemical cycles, including the carbon, oxygen, nitrogen, and phosphorus cycles. It explains that carbon, oxygen, hydrogen, and nitrogen make up over 99% of the Earth's biomass and cycles these and other elements through the biosphere, lithosphere, atmosphere, and hydrosphere. The key concepts of reservoirs, fluxes, residence times, and feedbacks are introduced. Human impacts like fossil fuel combustion and deforestation are noted to affect the natural carbon cycle. The nitrogen cycle is profoundly impacted by human fertilizer use and cultivation, while phosphorus cycling is accelerated by phosphate mining and fertilizer application.

Biogeochemical Cycles and Human Activities
A biogeochemical cycle is one of several natural cycles, in which conserved matter moves through the biotic and abiotic parts of an ecosystem. In geography and Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) compartments of Earth. The following presentation discusses the role of humans in the biogeochemical cycles.
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.
Lecture 6 biogeochemical cycles
The document discusses the oxygen cycle on Earth, including the major sources and sinks of oxygen. It notes that photosynthesis by plants and phytoplankton is the primary source of oxygen, producing about 30,000 teragrams of oxygen per year. Respiration by animals and decay of organic matter act as sinks and consume a similar amount, keeping atmospheric oxygen concentrations relatively stable over time.
Biogeochemical cycles
Biogeochemical cycles describe the cycling of essential nutrients like carbon, oxygen, nitrogen, phosphorus, and sulfur between the biotic (living) and abiotic (non-living) components of ecosystems. Energy from the sun drives these cycles as nutrients are exchanged between organisms, water, air, soil, and rock. Humans have disrupted natural biogeochemical cycles through activities like burning fossil fuels, clearing vegetation, using fertilizers, and pollution, which has contributed to issues like climate change and algal blooms.
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.
Biogeochemical cycle
Biogeochemical cycle, any of the natural pathways by which essential elements of living matter are circulated. The term biogeochemical is a contraction that refers to the consideration of the biological, geological, and chemical aspects of each cycle.

BiochemicalCycles.pptx
The document discusses three nutrient cycles - carbon, nitrogen, and water. The carbon cycle involves carbon dioxide entering the atmosphere through respiration and combustion, being absorbed by plants through photosynthesis, and passed along the food chain before eventually being released again as carbon dioxide through respiration and decomposition. The nitrogen cycle involves nitrogen in the air being converted to usable forms for plants by nitrogen-fixing bacteria and lightning, and being recycled between the atmosphere, soil, plants and animals. The water cycle involves water evaporating from surfaces, condensing in the atmosphere, falling as precipitation, running across or infiltrating into the soil, and transpiring from plants before evaporating again.

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.
NUTRIENT CYCLING IN NATURE.pptx
The document discusses several nutrient cycles that are important for plant growth. It focuses on the carbon, nitrogen, and phosphorus cycles. The carbon cycle describes how carbon is exchanged between the atmosphere, organisms, oceans, and geologic reservoirs through processes like photosynthesis, respiration, and rock weathering. The nitrogen cycle explains how nitrogen is fixed from the atmosphere into usable forms through lightning, industrial processes, and symbiotic bacteria. These fixed nitrogen sources are then incorporated into living tissues and recycled through the decomposition of organisms.
Nitrogen cycle
The nitrogen cycle describes the biological and physical processes by which nitrogen is converted between its various chemical forms and circulates between terrestrial, marine, and atmospheric ecosystems, driven largely by microbial activity such as nitrogen fixation, nitrification, and denitrification; nitrogen is essential but scarce for biological use, and the nitrogen cycle maintains its abundance through these processes of conversion between its inert atmospheric form and bioavailable forms incorporated into living tissues.
Nutrient Cycles
The document discusses nutrient cycles at multiple levels - within ecosystems, globally, and how they interconnect. At the ecosystem level, nutrients cycle between living organisms and non-living components like soil, water and atmosphere through various processes. Globally, nutrient loss from one ecosystem becomes a gain for others, and the cycling of elements like carbon, oxygen, nitrogen and water occur at the planetary scale through the biosphere, atmosphere and lithosphere. Human activities are increasingly impacting global nutrient cycles.
Cycling of materials in ecosystem
1) Carbon, water, nitrogen, and phosphorus cycle through ecosystems, with organisms using these elements and releasing them back into the nonliving environment through processes like respiration, decomposition, and erosion.
2) The water cycle involves water evaporating from plants and surfaces, condensing in the atmosphere, and falling as precipitation before infiltrating the ground and flowing into rivers and oceans.
3) In the carbon cycle, carbon dioxide is absorbed by plants and enters animals when they eat plants or each other, and it is released back through respiration and decomposition.

Carbon cycle
The carbon cycle describes the movement of carbon between the biosphere, atmosphere, oceans, and lithosphere. Carbon is exchanged through physical, chemical, and biological processes, with the largest pools located in the oceans and lithosphere. Human activities like burning fossil fuels and deforestation have significantly increased the amount of carbon dioxide in the atmosphere, disrupting the natural carbon cycle and global climate. Understanding the carbon cycle is important for studying biological and climate processes.
Ecology review 2
The document summarizes several natural cycles:
1) The carbon cycle involves carbon sinks like plants, forests and soil that absorb carbon, and carbon sources like combustion, respiration and decomposition that release carbon.
2) Nitrogen fixation converts inert nitrogen gas into bio-usable forms through atmospheric fixation by lightning or biological fixation by microbes and plants. Nitrification converts ammonia into nitrites and nitrates which plants can use but are soluble and can leach from soil.
3) The hydrological cycle describes the continuous movement of water above, on and below the Earth's surface, with the same amount of water circulating but individual molecules coming and going quickly.
Biogeochemical
The document summarizes several key biogeochemical cycles, including the carbon, nitrogen, sulfur, phosphorus, hydrologic, rock, and tectonic cycles.

Nitrogen cycle in aquatic ecosystem...................................
The nitrogen cycle is essential for life and involves the transformation of nitrogen between various forms through biological and physical processes. In aquatic ecosystems, nitrogen is cycled through four main processes: fixation by bacteria, decay of organic matter by microorganisms, nitrification by nitrifying bacteria, and denitrification by bacteria under anaerobic conditions. Imbalances in the nitrogen cycle can lead to toxicity issues for aquatic life from ammonia or nitrite accumulation. Maintaining the proper functioning of the nitrogen cycle is important for the balance and health of aquatic ecosystems.

Extinction ppt student template
The document discusses natural extinction versus accelerated or human-caused extinction. It notes that 99.999% of all species that have ever lived are now extinct, with natural extinction occurring through environmental disturbances, while accelerated extinction is caused by human activities like hunting, agriculture, habitat destruction, pollution, and international trade. It states that the current rate of extinction is 50,000+ species every 5-10 years, and if nothing is done 1/3 of all living things may be lost within 30 years. The document lists characteristics of extinction-prone species and questions if the reader with those traits is doomed.

The document provides an overview of key concepts from Chapters 13 and 14, including direct and indirect causes of deforestation, methods of harvesting trees, causes of extinction, logistic growth curves and their assumptions, maximum sustainable yield (MSY) versus optimum sustainable population (OSP), the International Whaling Commission (IWC) and its goals, characteristics of extinction-prone species, and three case studies on fisheries, fire management, and paper production.
Ch 13 and 14 student template ppt 2010
This document discusses forests, deforestation, wildlife management, fisheries, and endangered species. It notes that forests are economically and ecologically important but deforestation is a major environmental concern. Deforestation is driven by wood usage, which is predicted to double by 2050, and paper production, which uses 30% of the world's paper despite only 5% of the population. Unsustainable logging and fishing practices have depleted fish and whale populations. International agreements have established protections and regulations for fisheries, whaling, and endangered species to curb overexploitation and prevent extinctions.
Ch 12 ppt 2010
This document discusses sustainable agriculture and its environmental impacts. It covers topics like soil structure and erosion, sustainable farming practices like crop rotation and cover crops, integrated pest management, causes of desertification, and issues with factory farming. The key goals of sustainable farming are to conserve soil and water resources and minimize pollution. Practices that reduce soil erosion include contour plowing, terracing, shelterbelts, and low- or no-till plowing. Cover crops and crop rotation help maintain soil nutrients and prevent excess nitrogen runoff. Integrated pest management uses a combination of biological, cultural and targeted chemical controls. Desertification is worsened by poor farming, overgrazing, deforestation and climate change.

Specifically, it states that cows alone use 50% of agricultural land but only provide 18% of calories. It also discusses the water, pollution, deforestation, and greenhouse gas impacts of industrial animal agriculture. The document advocates for eating lower on the food chain to reduce these environmental impacts.
Ch 10 ppt
Ecological restoration involves facilitating natural succession to help an ecosystem recover from human disturbance. There are two types of succession - primary succession establishes ecosystems in areas with no prior ecosystem, like retreating glaciers, while secondary succession reestablishes ecosystems following disturbances like fires. Restoration is difficult for lands that have lost organic matter or been subjected to overuse, and there does not appear to be a permanent climax state, as gradual loss of nutrients occurs even in mature ecosystems.
Ch 9 ppt
This document discusses biological productivity and energy flow in ecosystems. It begins by defining biomass as the total amount of organic matter in an ecosystem, which increases through plant and animal growth. It then explains that ecosystems are open to energy flow, with energy entering as food and leaving as heat or being stored. The laws of thermodynamics state that energy is conserved but always moves to less organized states, increasing entropy. Energy flows in one direction and organisms are generally inefficient at utilizing energy for growth.
Island biogeography activity procedure
This document provides student instructions for an activity exploring the theory of island biogeography. Students will simulate habitat fragmentation by analyzing how bean "migrants" spread from a main ecosystem to four island habitats of varying sizes and distances. They will conduct five trials, recording the number of beans reaching each island and calculating averages and percentages. The goal is to observe how island characteristics like size and distance affect biodiversity, as measured by the number of migrant beans reaching different islands.

Ch 7 laws ppt
The Endangered Species Act (ESA) was enacted in 1973 as the most far-reaching law for endangered species preservation passed by any nation. It protects over 1000 animals and provides penalties for harming endangered species or their habitats. The ESA works by listing species, designating critical habitats, developing recovery plans, and reviewing federal agency actions. The Lacey Act, originally passed in 1900, was one of the earliest US laws aimed at wildlife protection and was expanded in 1981 and 1988 to prohibit illegal wildlife trade internationally and domestically. CITES is an international agreement between governments to ensure wildlife trade does not threaten species' survival. It lists species in three appendices based on protection level.
Ch 7 8 ppt 2010 student notes
This document discusses several key concepts related to biological diversity and biogeography:
1. It defines biological evolution as changes in inherited traits over generations and outlines some processes that lead to evolution like mutations, natural selection, genetic drift, and geographic isolation of populations.
2. It discusses factors that influence biodiversity like habitat diversity, species diversity, and environmental conditions. Greater biodiversity is seen in areas with more physically diverse habitats, moderate disturbance, and small environmental variation.
3. It outlines biogeography patterns seen on different continents and islands, explaining how continental drift, isolation, and adaptation to new environments has led to divergent evolution and speciation over time.
