The term biocenosis was coined by Karl Mobius in 1877. It describes the interacting organisms living together in a habitat (biotope). Based on the concept of biocenosis, ecological communities can take in various forms zoocenosis for the faunal community, phytocenosis for the flora community and microbiocenosis for the microbial community.

Nice is the ecological role and space that an organism fills in the ecosystem. The ecological niche involves both the place where an organism live and role that an organism carries out in its habitat e.g. A plant growing in garden along with soil, climate, sunlight, nutrients etc.

An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. The fundamental source of energy in almost all ecosystems is radiant energy from the sun. The autotrophs processes the light energy and use the energy stored within the simple carbohydrates to produce the more complex organic compounds. The flow of energy through the ecosystem drives the movement of nutrients within the ecosystem. Decomposers play a key role in many of these cycles, returning nutrients to the soil, water, or air, where they can be used again by the biotic constituents of the ecosystem.
