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. EXPLAIN IN 3 VERY SHORT SENTENCES

The phenomenon can be explained by the fact that energy is lost as it flows through trophic levels, resulting in less biomass at higher levels. Producers, such as plants, convert sunlight into energy through photosynthesis, making them the primary source of energy. As organisms consume each other, only a fraction of the energy is transferred, resulting in a decrease in biomass as we move up the food pyramid.

EXPLAIN BETTER AND SHORTER

The food pyramid shows less biomass at the top because energy is lost as it moves up levels. Plants, as primary producers, convert sunlight into energy, forming the base of the pyramid. As energy is transferred from one trophic level to the next, only a portion is retained, leading to a decrease in biomass at higher levels.

REWORD THE LAST SENTENCE

As energy flows through trophic levels, only a fraction is passed on, causing a decline in biomass at higher levels of the food pyramid.

The reason there's less biomass at the top of the food pyramid is because when animals eat other animals, only some of the energy gets passed on. This means that by the time we get to the top, there's not as much energy or biomass left. So, there are fewer animals at the top compared to the many plants at the bottom that provide the energy for the whole ecosystem.
