The smallest tier of the biomass pyramid is on the bottom in the sea. This is because the base of the sea's food chain is phytoplankton, which are small and abundant. As you move up the food chain, the amount of biomass decreases, resulting in a smaller tier at the top of the pyramid. In contrast, in other habitats such as forests and prairies, the base of the food chain is typically composed of plants which often have a larger biomass, resulting in a larger tier at the bottom of the pyramid.
