Biological Environment

An ecosystem is a biological environment consisting of all the organisms living in a particular area, as well as all the nonliving, physical components of the environment with which the organisms interact, such as air, soil, water and sunlight.sEcosystems are functional units consisting of living things in a given area, non-living chemical and physical factors of their environment, linked together through nutrient cycle and energy flow.

The services and goods an ecosystem provides are often undervalued as many of them are without market value. Broad examples include:

regulating (climate, floods, nutrient balance, water filtration)
provisioning (food, medicine, fur, minerals)
cultural (science, spiritual, ceremonial, recreation, aesthetic)
supporting (nutrient cycling, photosynthesis, soil formation).

(Organisation or Structural aspect of an ecosystem)

An ecosystem comprises of two basic components

i) Abiotic components and

ii) Biotic components

The relationship between the biotic components and abiotic components of an ecosystem is called 'holocoenosis'.

These include the non-living, physico - chemical factors such as air, water, soil and the basic elements and compounds of the environment.

Abiotic factors are broadly classified under three categories.
Climatic factors which include the climatic regime and physical factors of the environment like light, humidity, atmospheric...
