I believe that the amount of carbon stored in organisms decreases as you move up the food chain. This is because carbon constitutes the biomass of an organism which decreases as you move upward the food chain. Each link in a food chain is known as a trophic level. Trophic levels represent a feeding step in the transfer of energy and matter in an ecosystem. Biomass is the amount of organic matter comprising a group of organisms in a habitat. As you move up a food chain, both available energy and biomass decrease. Energy is transferred upwards but is diminished with each transfer from one trophic level to the next.
