Explanation:

An ecosystem can be described simply as the collection of all living and non-living components in a particular area. The living components of the environment are known as biotic factors. Biotic factors include plants, animals, and micro-organisms. An ecosystem is a self sustaining structural
and functional unit of the biosphere. The ecosystem may be large or small. Biomes are refers to the large regional and sub continental ecosystem characterized by the similarity in vegetation and climate. Energy cycles through the abiotic and biotic organisms to maintain balance within the ecosystem. The abiotic parts of an ecosystem include the non-living components, such as air, water and the basic compounds of the environment.
Climatic and edaphic factors are several abiotic components of an ecosystem.
