Ecology is the scientific analysis and study of interactions among organisms and their environment, such as the interactions organisms have with each other and with their abiotic environment.
Biocoenosis is an association of different organisms forming a closely integrated community.
Among the living components of the biogeocenosis are autotrophic organisms (photosynthesizing green plants and chemosynthesizing microorganisms) and heterotrophic organisms (animals, fungi, many bacteria, and viruses), and among the inert components are the atmosphere layer around the earth, with its gas and thermal resources and solar energy; and the soil, with its water and mineral resources and, in part, the weathering crust (water in the case of an aquatic biogeocenosis).
In ecology the term ecosphere can refer to the Earth's spheres, a planetary ecosystem consisting of the atmosphere, the geosphere (lithosphere), the hydrosphere, and the biosphere.
A population is a summation of all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding.
