Question

what will be the amount of energy available to the organism of second trophic level of food chain if the energy available at first tropic level is 10000 joules?

Answer 1

According to the 10 percent rule. 10% od 10000 J will be available to the second trophic level i.e. 1000 J

Answer 2

Energy available to second trophic level=10% of energy available at first trophic level
i.e                                                            =.10*10000
                                                                =1000 Joules
