Basically, the rhizosphere effect is a grouping of soil properties that change when in the effective vicinity of roots. Some of these effects are increased number of organisms (mostly bacteria and fungi) and decomposition rates.

There are several different disciplines within ecology. Those include animal ecology, population ecology, quantitative ecology, community ecology, and molecular ecology.

Ecology is usually considered to be a branch of biology that focuses on and studies living organisms. There are specialize branches of ecology that include conservation ecology, chemical ecology, applied ecology, and biogeochemistry.
