Question

Where does nitrogen go after an organisms dies?

Answer 1

When organisms die, decomposers return nitrogen to the soil as ammonia.

Answer 2

Decomposers return nitrogen to the soil as ammonia when organisms die. In a process known as denitrification, other soil bacteria convert nitrates into nitrogen gas, releasing nitrogen back into the atmosphere. Volcanoes and lightning are two sources of nitrogen in the biosphere. The first place where nitrogen may be found is in the atmosphere.
