Question

It the amount energy in the trophic level which includes snake is 5kJ in the given
food chain, then what will be the amount of energy in the trophic level
including grass?
Grass - Grasshopper - Frog Snake - Eagle
​

Answer 1

Answer:

Solution. According to the 10 per cent law, only 10 per cent of the energy available in a trophic level is passed on to the next level. Hence, if the amount of energy available at the fourth trophic level is 5 kJ, the energy available at the producer level will be 5,000 kJ: 5 → 50 → 500 → 5,000.
