Explain how the activities of some bacteria form a part of both the carbon and nitrogen cycles.?

carbon cycle


as consumer and decay organic C to inorg.


provide food for others, i.e org. to org. e.g that in stomach of cox


as others' food


some autotrphic bacteria make CO2 to become organic


N cycle


fix N


turn N to forms that can be absorbed ultilized by plant


release N from organic part
