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:

According to 10 percent law, 90% of the energy captured from the previous trophic level is lost to the environment and only 10 percent is made available to the next trophic level. In this food chain, at the 4th trophic level, 5 kJ energy is available to the snake.

⟹ Energy available to Frog = 10% of 50 kJ

⟹ Energy available to Grasshopper = 10% of 500 kJ

⟹ Energy available to Grass = 10% of 5000 kJ.
