Solution
The correct option is D Eagle
Sun is the ultimate source of energy for all living organisms. Solar energy is directly absorbed by plants. A part of this energy is transferred to the herbivores that feed on plants. Of the total energy obtained by a herbivore from plants, only a portion is transferred to carnivores. So, as the food chain progresses, the amount of energy flowing into the organism also decreases. Hence, in the given food chain, grass has the highest energy and eagle has the lowest.
