Question

List different bacteria with their function in a nitrogen cycle.

Answer 1

Answer:

Bacteria play a central role:

Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates.

Bacteria of decay, which convert decaying nitrogen waste to ammonia.

Nitrifying bacteria, which convert ammonia to nitrates/nitrites.

Denitrifying bacteria, which convert nitrates to nitrogen gas.

Fungi, like bacteria, help to convert dead plants and animals and their wastes into ammonia in the soil.

Plants absorb nitrates from the soil to make proteins.

Animals consume plants and use it to form animal protein.

Humans contribute to the cycle by adding nitrogen rich fertilisers to the soil and by using manure
