In a food pyramid, there is typically less biomass at the top (i.e., there are very few individual tertiary consumers, whereas there are numerous individual producers). In three to five sentences, explain this phenomenon, citing evidence relating to energy flow and how plants support ecosystems.

The reason for less biomass at the top of a food pyramid is because of the loss of energy as you move up the trophic levels. Producers, such as plants, convert the sun's energy into usable energy through photosynthesis. However, only a small portion of that energy is stored in their tissues because they lose energy through respiration and other metabolic processes. When herbivores consume the plant, they only retain about 10% of the energy from the plant due to energy loss during metabolism. The same phenomenon occurs when carnivores eat herbivores. This means that there is less biomass and fewer individual organisms at the top of the pyramid since there is less energy available to support them.
Um just 3 to five sentences sooooooooo... also can you write it as if a 7th grader wrote it
Bot can u pls write it as if a 7th grader wrote it for this exact question
