Nitrogen Cycling for Forest Ecosystem

Assume that nitrogen cycling in a deciduous forest ecosystem is complete and involves all the producers, consumers and nitrogen fixing, denitrifying and ammonifying bacteria described in lecture

a. Trace an atom of N (N15) that was released into the atmosphere of the forest through
its route to a bacterial cell that releases it back to the air.

b.Suppose that decompsers were removed from the forest ecosystem, predict what
would happen to the rate of nitrogen cycling. Explain the logic behind your prediction.
