Question based on paragraph A class of students was taken on an excursion by the school to the banks of a river. They were explained that energy can be transferred from phytoplanktons to humans. This pattem of energy in the ecosystem could be explained as a ‘pyramid of energy’. The pyramid of energy consists of phytoplanktons at the bottom, followed by three successive trophic levels consisting of zooplanktons, fishes and humans respectively. There is a gradual crease of energy and number of organisms from the base to the apex of the pyramid. The passage of energy is referred to as ‘one way’ transport. Based on the above passage, answer the question If the aquatic ecosystem has 10,000 kcal concentrated by phytoplanktons, how much energy will be transferred to humans?
