In the given food chain, suppose the amount of energy at fourth trophic level is 5 kJ, what will be the energy available at the producer level ?
`"Grass"to"Grasshopper"to"Frog"to"Snake"to"Hawk"`

A

5 kJ

B

50 kJ

C

500 kJ

D

5,000 kJ

Text Solution

Verified by Experts

The correct Answer is:
D
According to 10% law, only 10% of energy is transferred to the next trophic level and remaining 90% energy is used in life processes by present trophic level.

Therefore, Energy available to Grass = 10% of 5000 kJ.
Energy available to Grasshopper = 10% of 500 kJ
Energy available to Frog = 10% of 5000 kJ = 50 kJ
Energy available to Hawk= 10% of 50 kJ = 5 kJ
