Question

lf 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

(a) 0.02 J  (b) 0. 002 J  (c) 0. 2 J  (d) 0.0002 J

Answer 1

Correct option (c) 0. 2 J 

 Explanation:

 According to 10% law of energy flow by Raynold Lindeman. The total amount of energy, that can be transferred to the next trophic level is the 10% hence, peacock will receive 0.02 J of energy as top consumer,

 Energy received by other organisms are

 Plant →  20 J

 Mice → 20 x 10% =2 J

Snake →  2 x 10% = 0.2 J
