Question

in the following food chain suppose the amount of energy at fourth tropic level is 5KJ calculate the amount of energy available at producer level and primary consumer​

Answer 1

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.
