Water Cycle
The process animals use to take in water.
drinking/eating
The process by which carbon enters the hydrosphere.
marine photosynthesis and respiration
Processes that add nitrogen to the lithosphere.
bacterial nitrogen fixation, deposition and excretion
The way phosphorus enters the atmosphere.
It doesn't!
The process by which water enters plants to later be evaporated.
root uptake
Feeding
Process by which nitrogen enters to the hydrosphere through nitrates and nitrites.
Incorporated into marine producers and reused.
The process by which phosphorus enters the lithosphere.
deposited in ocean sediments and through decomposition of organic material
The process by which water changes from a liquid form to an atmospheric gas.
Evaporation
The way carbon enters plants.
photosynthesis
The way animals take up nitrogen in the form of nitrates and nitrites.
Consumers eat nitrogen-containing producers
The process by which phosphorus enters the hydrosphere.
Runoff from phosphorus-containing rocks.
The process by which water enters the lithosphere.
Seepage
Three ways carbon enters the atmosphere.
respiration, human activity, and volcanic activity
The process by which plants take up nitrogen.
Incorporate nitrites and nitrates in their proteins
The process by which phosphorus enters an animal.
Feeding on phosphorus-containing producers
The process by which water reenters the hydropsphere.
Runoff
Two ways carbon enters the lithosphere.
decomposition of dead matter and deposition as fossils
The process by which carbon enters the atmosphere as a gas.
detrification
The process by which phosphorus enters a plant.
Incorporated into organic compounds as phosphate
