(05.02 mc)the diagram below shows a marine food chain with the amount of energy available to each trophic level in parentheses. why does the amount of energy decrease as you move up the chain? a pyramid showing the marine food chain indicating the amount of energy available to each trophic level. at the top of the pyramid, level 5 shows tuna at an energy level of 0.5. trophic level 4 has mackerel at an energy level of 5, trophic level 3 has herring at an energy level of 50, followed by trophic level 2 with zooplankton at an energy level of 500 and phytoplankton at the bottom with an energy level of 2500.a: decomposers are using up the energy between each trophic level.b: individual organisms at the upper trophic levels require less energy to survive than those at the lower ones.c: producers use most of the energy before it can reach the upper levels.d: some energy is lost as heat or not consumed by organisms at the next trophic level.
