Q 70. If 20 J of energy is trapped at producer level, then how much energy will be available to peacock as food in the following chain? Plant → mice → snake → peacock Option A 0.002 J Option B 0.2 J Option C 0.0002 J Option D 0.02 J
Q 70. If 20 J of energy is trapped at producer level, then how much energy will be available to peacock as food in the following chain? Plant → mice → snake → peacock Option A 0.002 J Option B 0.2 J Option C 0.0002 J Option D 0.02 J

Correct Option: D

Solution: Law of 10 percent is applied

Energy trapped at producer level, plant = 20 J

Energy trapped by mice = 20 x 10% = 2 J

Energy trapped by snake = 2 x 10% = 0.2 J

Energy trapped by peacock = 0.2 x 10% = 0.02 J
