Question

If 5 joules of energy is available at producer level (plants), then how much energy will be transferred to the lion in the following food chain?​ ​

Plants → Goat → Lion​ ​

Answer 1

Solution:-​ ​

According to the 10% law, only 10% of energy is transferred from one trophic level to the succeeding trophic level.​

​ So, if the plant has 5 joules of energy available, only 10% of it will be received by the goat, i.e., 0.5 joules.​ ​

The lion will get only 10% of the energy available with the goat, i.e., 0.05 joules of energy.​ ​
