Nitrogen Cycle
What are the 5 major transformations within the nitrogen cycle?
the release of water from leaves into the atmosphere during photosynthesis.
What is transpiration?
This phase does not exist in the phosphorus cycle.
What is the gas phase?
Rocks under the ocean
What is the largest carbon reservoir?
The movements of matter within and between ecosystems involving cycles of biological, geographical, and chemical processes.
What is a Biogeochemical cycle?
The process that converts nitrogen fas from the atmosphere into forms of nitrogen that plants and algae can use. Can be biotic or abiotic.
What is nitrogen fixation?
The combined amount of evaporation and transpiration.
What is evapotranspiration?
Where the slow part of the carbon cycle takes place.
What is Carbon that is held in rock or soil?
A nutrient required for the growth of an organism but available in a lower quantity than other nutrients.
What is a limiting nutrient?
What is nitrogen through leaching?
When water soaks into the ground.
What is infiltration or percolation?
What are the major phosphorous reservoirs?
Rocks and sediments
An anthropogenic concern about the Carbon Cycle
What is the combustion of CO2?
The percent of the atmosphere that is Nitrogen
The process by which plants and algae incorporate nitrogen into their tissues.
What is assimilation?
Water that moves across the land surface and into streams and rivers.
What is runoff?
When oxygen concentrations become so low that it kills fish and other aquatic animals.
What is a dead zone?
Forms when CO2 dissolves in the ocean and combines with calcium ions. It can precipitate out of water and from limestone through the processes of sedimentation and burial.
What is Calcium Carbonate?
This sources of phosphorus has been widely banned.
What is detergents containing phosphorus?
The conversion of nitrate in a series of steps into the gasses nitrous oxide and eventually nitrogen gas which goes into the atmosphere.
What is denitrification?
This is caused by humans building roads and other construction.
What is Increased runoff?
What are Assimilation, mineralization, sedimentation, geologic uplift, and weathering?
The 7 processes that drive the carbon cycle.
What are photosynthesis, respiration, exchange, sedimentation, burial, and extraction?
The equation to find Net Primary productivity.
what is GPP-R= NPP.
