Question

If a food chain consisting of four trophic level started with the energy of 4000 KJ then, how much energy is available to the organism at the secondary level?​

Answer 1

Answer:

According to the 10 percent law, only 10% of the energy is transferred to each trophic level from its lower trophic level. If 10,000 joules of energy is available to the producer, then only 1000 joules of energy will be available to the primary consumer and only 100 joules of energy will be available to the secondary consumer. The energy available with the tertiary consumer will be 10 joules of energy.
