Detailed explanation-1: -Ecosystem: The collection of all living organisms in a geographic area, together with all the living and non-living things with which they interact.

Detailed explanation-2: -Community: A biological community consists of all the populations of different species that live in a given area.

Detailed explanation-3: -Symbiosis is an interaction characterized by two or more species living purposefully in direct contact with each other. The term “symbiosis” includes a broad range of species interactions but typically refers to three major types: mutualism, commensalism and parasitism.

Detailed explanation-4: -A community is all of the populations of different species that live in the same area and interact with one another. A community is composed of all of the biotic factors of an area. An ecosystem includes the living organisms (all the populations) in an area and the non-living aspects of the environment (Figure below).

Detailed explanation-5: -The populations of all the different species that live together in an area make up an ecological community. Community ecologists examine how different species in a community interact with each other. Interactions between two or more species are called interspecific interactions.
