Question

In a given food chain, suppose the amount of energy at fourth trophic level is 5kj, what will be the energy available at the producer level grass >> grasshopper >> frog>>snakes>>hawk

Answer 1

Only 10% of the energy present is given to the consumer in the next level, of the total energy the level/animal has.

Therefore , if 4th Level = 5kJ

3rd Level = 50kJ

2nd Level = 500kJ

Producer = 5,000kJ
