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

This phenomenon can be explained by the laws of energy flow and trophic levels in an ecosystem. Energy is transferred between trophic levels, starting from producers (plants) who convert solar energy into chemical energy through photosynthesis. As energy is transferred from one trophic level to the next, there is a loss in energy through metabolic processes and heat production. This means that less energy is available for the organisms at higher trophic levels, leading to lower biomass at the top of the pyramid. Additionally, plants support ecosystems by providing food, shelter, and oxygen, which allows for the proliferation of numerous individual producers compared to tertiary consumers.
