In the following food chain, only 2J of energy was available to the peacocks. How much energy would have been present in Grass? Justify your answer. GRASS→GRASS→HOPPER→FROG→SNAKE→PEACOCK |
|
Answer» Energy present in Grass = 20000J Justification: According to the ten percent law of energy in a food chain, only ten percent of energy is transferred to the next trophic level. Thus, the energy keeps on decreasing by 10% at each level. If, Energy available to grass = 20000J Energy available to grass hopper = 10% of 20000 = 2000J Energy available to frog = 10% of 2000 = 200J Energy available to snake = 10% of 200 = 20J And Energy available to peacock = 10% of 20 = 2J Hence, justified |
