BioGeoChemical Cycle Flashcards
Energy flows directionally through ecosystems, entering as ____
Sunlight
Energy flows directionally through ecosystems, entering as sunlight (or inorganic molecules for ____
Chemoautotrophs
The six most common elements associated with organic molecules—
carbon, nitrogen, hydrogen, oxygen, phosphorus, and sulfur
Geologic processes that all play a
role in this recycling of materials. (4 processes)
weathering
erosion
water drainage
subduction of the continental plates
Because _______ and _____ have major roles in the
study of this process, the recycling of inorganic matter between living organisms and their
environment is called a biogeochemical cycle
Geology and Chemistry
Because geology and chemistry have major roles in the
study of this process, the recycling of inorganic matter between living organisms and their
environment is called a ______
Biogeochemical Cycle
the area of the Earth where water movement and storage occurs: as liquid water on the surface and beneath the surface or frozen (rivers, lakes, oceans, groundwater,
polar ice caps, and glaciers), and as water vapor in the atmosphere.
Hydrosphere
Element that is found in all
organic macromolecules and is an important constituent of fossil fuels.
Carbon
Element is a major
component of our nucleic acids and proteins and is critical to human agriculture.
Nitrogen
Element that is a major component of nucleic acid (along with nitrogen), is one of the main ingredients in artificial fertilizers used in agriculture and their associated environmental impacts on our surface water.
Phosphorus
Element that is critical to the 3–D folding of proteins (as in disulfide binding), is released into the atmosphere by the burning of fossil fuels, such as coal.
Sulfur
It is the process by which constituents of a solid material are released into a contacting water phase, nitrogen and phosphate into rivers, lakes, and oceans.
Leaching
Major reservoir for carbon
Ocean
True or False: mineral nutrients are cycled, either rapidly or slowly, through the entire biosphere, from one living organism to another, and between the biotic and abiotic world.
True
