Atmosphere78% of the

atmosphere is nitrogen

Plants and animals cannot use the nitro gen in the atmosphere

Nitrogen-fixed bacteriaThe nitrogen from

the atmosphere turns into a compound of nitrogen and hydrogen

PlantsThe plants produce

bacteria so the decomposers give out nitrogen

The nitrogen then helps the plants grow

AnimalsAnimals produce

nutrients for the soil that helps the plants grow

Then the decomposers get eaten by bacteria from the plants

DecomposersThe decomposers

break down from the bacteria that plants produce

Then they give off nitrogen
