Question

1. Observe the food chain given below: Grass  Grass hopper  Frog  Snake  Eagle. If the energy available at second trophic level is 5000 J, then the amount of energy available for snake is (A) 500J (B) 5J (C) 0· 5J (D) 50J.

Answer 1

Answer:

500 j is the correct answer of this

Answer 2

according to 10%law only 10%of the energy is transferred from each trophic level. so the frog gets 10%of 5000which is 500J. The snake gets 10%of 500J which is 50J. Therefore option d is correct.
