9/16 Step 3 Nitrogen Cycle CFU AP

Nitrogen Gas found in the atmosphere

Decomposition of plants and animals return nitrogen to the soil

Bacteria in the roots of plants turn nitrogen gas into a “useable” form called ammonia. The plants then take in the ammonia through assimilation.

Assimilation of nitrogen by animals by eating plants

Nitrogen gas is created through denitrification by bacteria in the soil

Excess carbon in water

Excess nitrogen and phosphorus in water

Excess oxygen in water

Consumes oxygen through decomposition and blocks sunlight

Prevents photosynthesis of terrestrial plants due to toxic buildup

Causes an overgrowth of animal life due to an abundance of food
