Whether you’re interested in bio geo cycles, or biogeo cycles, or even biogeocycles, you’re probably looking for information about Biogeochemical Cycles.
Here’s the definition of Biogeochemical Cycles, courtesy of Wikipedia:
In ecology and Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical element or molecule moves through both biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) compartments of Earth.
Elements, chemical compounds, and other forms of matter passed from one organism to another and from one part of the biosphere to another through biogeochemical cycles. Matter is recycled within and between ecosystems.
Plants play an important role in the Phosphorus Cycle – they absorb phosphates from the soil or water and bind them into organic molecules that can be used by animals.
Here are some terms you need to learn when you study topics related to biogeochemical cycles:
- agal bloom
- ecological pyramid
- fossil fuels
- limiting nutrient
- nitrogen fixation
- primary productivity
- rocks and sediments that have been broken down
- trophic level
The above terms match with the following (can you correctly pair them?):
- a collection of all the organisms that live in a particular place, together with their nonliving, or physical, environment
- a diagram that shows the relative amounts of energy or matter contained within each tropic level in a food chain or food web
- a group of ecosystems that have the same climate and similar dominant communities
- assemblage of different populations that live together in a defined area
- breaks down organic matter
- chemical symbol for nitrates
- coal, oil, natural gas, and other fuels that are ancient remains of plants and animals.
- converting nitrogen gas into ammonia
- during this autotrophs use light energy to power chemical reactions that convert carbon dioxide and water into oxygen and energy-rich carbohydrates such as sugars and starches
- each step in a food chain or food web
- feed on plant and animal remains and other dead matter
- group of individuals that belong to the same species and live in the same area
- group of organisms so similar to one another that they can breed and produce fertile offspring
- how animals and plants use energy
- how does energy flow?
- set apart from others
- the chemical symbol for ammonia
- the main energy source for life on earth
- the rate at which an organic matter is created by producers
- the total amount of living tissue within a given trophic level
- this process is when soil bacteria converts nitrates into nitrogen gas and releases nitrogen into the atmosphere
- this process releases nitrogen gas into the atmosphere once again
- using CO2 and H2O to make O2 and carbohydrates
- wearing away soil with water or wind
- when an aquatic ecosystem receives a large input of limiting nutrient this is the result
- when an ecosystem is limited by a single nutrient that is scarce or cylces very slowly
- when bacteria converts Nitrogen gas into ammonia
- when organisms use chemical energy to produce carbohydrates
- where do phosphates usually come from?
