Answer
The self-regulating and self-sustaining structural and functional unit of the biosphere is called an ecosystem. This system depends upon the sun for its energy.
For example, Ecosystem of a forest include plants and trees which are eaten by herbivores (deer, rabbit). These animals are eaten by carnivores (lion, tiger). When these animals perish, they are decomposed by decomposers and return to the environment. Again they are consumed by producers and so on.
