Human Impacts on Biogeochemical Cycles

From there, the phosphorus is drawn in from plants and then turned into an organic phosphate that is eaten by consumers. Plants take nitrogen from the soil by absorption through their roots.

The main reservoir for the phosphorus cycle is in sediments, unlike the nitrogen and carbon cycles, where the main reservoir is in the atmosphere. Carnivores then eat the other animals thus releasing carbon in animals.

Phosphorus is an important mineral nutrient needed in all ecosystems, it is used as fertilizer to hasten plant blooming as well as used in plant production, which in turn is a key element needed for animals and humans.

It is a level environmental science course. Usually, the nitrogen must be in the form of a chemical called nitrate. This will repeat the cycle. Many plants are able to use ammonia directly. As learned by the Law of Conservation of Matter, atoms cannot be destroyed or created, instead they recycle themselves, so these cycles show how the different types of atoms are transformed and used by consumption.

Too much nitrogen in the atmosphere can contribute to ozone depletion, global climate changes, and ozone pollution. This process is called nitrification and completes the main part of the cycle. Humans impact this cycle dramatically through industrialization and over consumption, resulting in more than double the natural amount of nitrogen from the atmosphere into the soil.

In death their bodies are consumed by scavengers which will release the carbon back into the air or stay deposited in the earth, which can then turn into coal or another fossil fuel that will be burned, releasing the carbon back into the air to finish its cycle.

There are three biogeochemical cycles that humans impact daily: More recently, reforestation and changed agricultural practices have improved this somewhat. In this cycle you could start with the large amounts of carbon that is in the atmosphere and which is then pulled in from plant life and turned into organic matter oxygen that helps animals breath.

Where this cycle is unique is how the nitrogen is then turned useable again by bacteria called nitrifying bacteria. Plants use it to perform photosynthesis and make food.

Overuse or careless use of phosphorus fertilizers are examples of human interference in the phosphorus cycle. When people use synthetic fertilizers on crops such as corn, wheat potatoes, and cotton nitrites or nitrates are added into the soil.

With most phosphorus getting trapped essentially in the ocean, ocean life becomes tainted with over fertilization that can lead to death of plant and animal life. Human actions have more than doubled the rate at which nitrogen is moved from the atmosphere to the land.

This results in increased amounts of phosphorus as pollutants in bodies of water resulting in eutrophication.

Applying Chemistry to Society, C. Students will gain experience in reading and interpreting published scientific papers and will use literature to build systems models. The course content is chosen to directly apply basic science concepts to understanding local, national and global environmental challenges.

Students will be proficient in concepts of general chemistry and use these concepts to explain environmental phenomenon, both qualitative and quantitative. This format demands teaching outside of standard lecture styles.

It is a challenging course for our policy majors and is intended to give them working knowledge of the strengths and limitations of computational modeling, as well as an increased ability to read and digest peer-reviewed scientific literature.

Students also take American Chemical Society standardized chemistry examinations to ensure that students are gaining a sufficient qualitative and quantitative background in general chemistry. Humans are cutting down forests for an ever-growing population which is lessening the amount of CO2 transferred to oxygen, lowering our air quality.Biogeochemical Cycles Introduction The relationships between agriculture and nature have always been painful.

While agriculture and animal breeding were the reliable sources of plant and animal food, nature was suffering the consequences of human unreasonable approaches to fertilization. Running head: BIOGEOCHEMICAL CYCLES 2 Climate Change and the Human Factor Climate change is having, and will continue to have, impacts on biogeochemical cycles, which will alter future impacts on climate and affect our capacity to cope with coupled changes in climate, biogeochemistry, and other factors.

With environmental rhetoric gaining increasing currency in the contemporary zeitgeist, it is commonly supposed that we have a moral responsibility to protect ecosystems and conserve biodiversity, particularly from the ecologically devastating impacts of a human civilization that depends on industrial systems and the capitalization of natural resources.
