A physical environment with different species that interact with one another and with nonliving things is called an ecosystem.

Ecosystem is the functional unit of nature. An ecosystem can be different in size according to the communities living in that ecosystem. Abiotic and biotic components together make an ecosystem.

Chemical and physical factors come under abiotic components. Physical components like water, air, light, temperature have more effects on the ecosystem than chemical factor.

Organisms are the biotic component of an ecosystem. They can be autotrophs or heterotrophs. Many organisms make a population, many populations combine to form community and many communities combine to form an ecosystem.
