Answer 1

Answer: (B)

Both Assertion and Reason are true, but Reason is rot the correct explanation of Assertion. AG Tansley coined the term ecosystem (Gr. Ecoenvironment; system - interaction and interdependent complex) for the first time. It is an integrated natural system resulting from the interaction of living and ron-living factors of the environment. In other words, the ecosystem can also be defined as an inter-relationship between biotic (living) and abiotic (non-living) components of the environment.
