Question 21

Nitrogen Cycle

Answer 21

INSIDE
-animal/plant waste
-decomposers break down waste and release nitrogen into the soil
-uptake of nitrogen by plants
-consumers eat plants containing nitrogen ^
OUTSIDE OF CYCLE
free nitrogen in the air
bacterias in roots convert free nitrogen to compounds
bacteria release some free nitrogen back into air ^
