What happens to nitrogen when plants and animals die? (2 correct answers)
It is absorbed by plants immediately
It is turned into carbon
Some of it is released back into the atmosphere by decomposers
Some of it stays in the soil and helps fertilize plants.
How do humans influence the nitrogen cycle?
By using fertilizers containing nitrates
By planting more trees
By reducing fossil fuel consumption
By absorbing nitrogen directly from the air
What are the two major processes involved in the carbon cycle?
