Model Answer

(B) All interacting organisms in an area together with the non-living constituents of the environment.

Explanation

The textbook explicitly defines an ecosystem as "all the interacting organisms in an area together with the non-living constituents of the environment." Options A and C describe only parts (biotic or abiotic), and D describes just one component (food chains). Always remember: ecosystem = biotic + abiotic components together.
