Answer 1

As energy flows through ecosystems, atoms and molecules cycle among (D) both the living and the nonliving components of the biosphere.

 Energy flow in the ecosystem starts with the sun. It then flows via a food chain process.

The energy released by the sun is taken up by organisms that make their own food i.e. the autotrophs.

The organisms or called heterotrophs, which cannot make their own food eat up the food made by autotrophs and then get eaten by another heterotroph.
