Rafael Reynolds · Answer 1

Bacteria alter the nitrogen from decomposing bodies of other organisms into a form that plants are able to use.

Faith Ferguson · Answer 2

All plants and animals need nitrogen to make amino acids, proteins, and DNA, but the nitrogen in the atmosphere is not a form that they can use. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use.
