The gloval movement of carbon between organisms and the abiotic environment including the atmosphere, ocean and sedimentary rock
What is the carbon cycle
100
This is the term for the conversion of gaseous nitrogen to ammonia
What is nitrogen fixation
100
This is a group of phosphate containing minerals that are often found as small green, yellow or blue crystals in rocks
What is apatite
100
These are the places most sulfur is found
What is sedimentary rocks and minerals
100
Hydrologic is also known as this
What is water
200
This process removes CO2 from the air and fixes in into chemical compounds such as sugar
What is photosynthesis
200
This is crucial for all organisms because it is an essential part of the biological molecules shuch as proteins and nucleic acid
What is nitrogen
200
this is the process where phosphorus containing minerals release phosphorus into the soil
What is erosion
200
This is an example of minerals that relase sulfur containing compounds into the ocean as they erode over time
What is gypsum or anhydrite
200
This is the term for the loss of water vapor from land plants
What is transpiration
300
The 1st step of the carbon-silicate cycle involves what chemical process
What is weathering processes
300
This is the conversion of ammonia to nitrate
What is nitrification
300
This is how dissolved phosporus enters equatic communites when algae and plants are consumed by plankton and larger organisms
What is absorption and assimilation
300
When hydrogen sulfide reacts with oxygen these are formed
What is sulfur oxide
300
This is known as the movement of water from land to rivers, lakes, wetlands and oceans
What is runoff
400
This process returns barbon back inot the atmosphere
What is combustion
400
This is the process when animals consume plant tissue and convert nitrogen complounds and convert them to animal proteins
What is assimilation
400
This is the porcess where phosphorus goes from the environment to living organisms, back to the environment
What is the phosporus cycle
400
these are known for driving the sulfur cycle
What is bacteria
400
this is the area of land drained by runoff
What is a watershed
500
This has been linked with a rise in sea leverl, change in precipitation patterns, death of forests, the extinction of organisms and problems or agriculture
What is global climate change
500
This is the conversion of biological nitrogen compounds into ammonia and ammonium ions
What is ammonification
500
Phosphorus that washes from the land into the ocean for practical purposes for practical purposes is viewed as this
What is permanently lost
500
Sulfure from the environment to living organisms and back to the environment is known as this
What is the sulfur cycle
500
Water that seeps down through the soil and rock is known as this
