Vedclass · Answer

(A) natural ecosystem is defined as a self-regulating and self-sustainable unit of nature.It is self-sustainable because it contains all the necessary functional components: producers (to capture solar energy),consumers (to transfer energy),and decomposers (to recycle nutrients).The presence of these components ensures the continuous flow of energy and the cycling of nutrients,which allows the ecosystem to maintain its structure and function independently.Therefore,both the assertion and the reason are true,and the reason provides the correct explanation for why a natural ecosystem is self-sustainable.
