Question

draw three food chains and explain the energy flow in different levels

Answer 1

your first answer ^^^


The energy decreases as you move through the trophic levels from the bottom to the top of the energypyramid. This is because the energy is used up by the organisms at eachlevel. The pyramid shape is used to represent the flow of energy because of the way that energy is used up and lost throughout the system



flow chart is in last ....
