association with the
help of examples.

Symbiosis is a close relationship between two species in which at least one species benefits. There are three types of symbiotic relationship, which are; Mutualism, Commensalism and Parasitism.

Explanation:

Parasitism is a symbiotic relationship in which one species (the parasite) benefits while the other species (the host) is harmed. Example, a tick (parasite) living on a livestock (host).

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.
