Examples of biotic factors are

- grasses in an habitat

- mushroom on a piece of wood

- goats in the farm

All living Organism within the ecosystem

Explanation: Biotic factor are living organism within the ecosystem that affects other organism.

They are grouped into producer,consumer,decomposer

Producers are autotrophs,they produce their own food

Consumer depends on producers for their food and are called heterotrophs while decomposer are microorganisms that extract chemicals from producers and consumers .Example of Biotic components are plant,animals,microorganisms

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
