Calculate the amount of energy available to tiger in the following food chain if plants have 30,000 J of energy available from the Sun:
Plant—> Deer—> Tiger
Answer:
Plants can trap only 1% of the Sun’s energy falling on them. Now, 1% of 30,000 J is 300 J which is the energy available to plants.
The plants are eaten up by deer. According to 10% law, 10% of 300 J, i.e., 30 J of energy will be available to deer as food.
The deer will transfer 10% of its 30 J energy to the tiger. Thus, the food energy available to the tiger will be 10% of 30 J which is 3 J.
