Correct Answer: C
Explanation:
): Each successive level of nourishment as represented by the links of the food chain is known as a trophic level. The plant producers within an ecosystem constitute the first trophic level, the herbivores form the second trophic level, and the carnivores represent third level. Additional links in the main food chain and inside chains such as those formed by parasites constitute further trophic levels. In a terrestrial ecosystem maximum energy is in trophic level because the organisms which trap solar energy are primary producers and they have got maximum energy. Only 10% energy is transferred from one trophic level to next trophic level
