Breakdown of dead/decomposing materials into ammonia?

Breakdown of dead materials into ammonia occurs due to decomposers.

Explanation:

Decomposers are the organisms which are responsible for the breakdown of dead bodies of plants and animals produces ammonia by consuming the nitrogen present in that dead body of plant and animals through the process of ammonification. The ammonium produced is then converted into nitrates by the nitrifying bacteria and this nitrates is used by the plants for making amino acids and enzymes.

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.
