What are some differences between a food chain, web, or energy pyramid? Food chains show a limited feeding relationship between only a few organisms. Energy pyramid is the visual representation of the amount of energy, population, or biomass at each trophic level.
A food chain represents the linear relationship between organisms for food. On the other hand, a food pyramid represents the optimal number of servings to be eaten each day from each of the basic food groups
fat cells have many mitochondria because they store a lot of energy. Muscle cells have many mitochondria, which allows them to respond quickly to the need for doing work.
The rate of a reaction is the speed at which a chemical reaction happens. If a reaction has a low rate, that means the molecules combine at a slower speed than a reaction with a high rate.
