Question
Observe the given figure and answer the questions:Image1. Which trophic level has maximum energy?
2. Why carnivores have least energy shown in this diagram?

Answer

1. Producers which form first trophic level has maximum energy.
2. When energy flows from one trophic level to the next, some amount is lost as heat. As it can be seen that producers had 1000 joules of energy, out of which 900 joules are lost when energy flowed from producers to primary consumers. Further, it was lost again by 90 joules while herbivore to carnivore energy flow was taking place. Therefore, the carnivore gets least energy as it is the higher trophic level.
