As a cell gets bigger, diffusion becomes less efficient because the surface-to-volume ratio decreases. As the sphere or animal gets bigger, the surface area for diffusion gets smaller.
<h3>Describe a cell example:</h3>
All of these plants and animals, including trees in a forest, fish in a river, horseflies on a farm, lemurs in the jungle, reeds in a pond, and worms in the soil, are comprised of the building blocks known as cells. Many living organisms, like these examples, are made up of many cells cooperating with one another.

Answer:
Notice that at each level of the food chain, about 90% of the energy is lost in the form of heat. The total energy passed from one level to the next is only about one-tenth of the energy received from the previous organism.
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. A food chain can usually sustain no more than six energy transfers before all the energy is used up.
