In most ecosystems, the pyramid of numbers is upright, meaning that there are more organisms at the lower trophic levels than at the higher trophic levels. This is because it takes many plants to support a single animal, and it takes many animals to support a single human.<\/p>\n<p>A pyramid of biomass is a graphical representation of the total mass of organisms at each trophic level in a food chain. In most ecosystems, the pyramid of biomass is also upright, but it can be inverted in some ecosystems. For example, in a tree-dominated ecosystem, the biomass of the trees is much greater than the biomass of the animals that eat the trees. This is because trees are long-lived and have a high mass, while animals are short-lived and have a low mass.<\/p>\n<p>A pyramid of energy is a graphical representation of the total energy at each trophic level in a food chain. In all ecosystems, the pyramid of energy is always upright. This is because energy is lost at each trophic level as heat. For example, only about 10% of the energy from the plants is transferred to the herbivores that eat them. Only about 10% of the energy from the herbivores is transferred to the carnivores that eat them. This process continues up the food chain, so there is always less energy at the higher trophic levels.<\/p>\n<p>Therefore, the only option that is not correct is B. In tree dominated ecosystem the pyramid of numbers is inverted.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Join Our Telegram Channel Subscribe on
