What relationship exists between trophic levels and why is there less biomass at the top of the energy pyramid?
Rk Naresh
Food chains and trophic levels both look at what an organism does for energy. As you move up a food chain, you are typically moving into a higher tropic level, and all food chains have essentially the same tropic levels. At the bottom of the food chain are plants. The number of organisms at each level decreases relative to the level below because there is less energy available to support those organisms. The top level of an energy pyramid has the fewest organisms because it has the least amount of energy.
