Why is it important for nitrogen to be recycled in an ecosystem?
Nitrogen is one of the elements present in nitrates which is a mineral that plants need for growth. Nitrogen fixing soil bacteria take the nitrogen from the air and change it into ammonium, and then further changed by nitrifying bacteria into nitrates. these nitrates are then taken up by the plants.
