Energy loss between trophic levels

Back

10 percent

Answer explanation

When energy is transferred from one trophic level to the next, about 90 percent of the energy is lost, primarily as heat. This means only about 10 percent of the energy is passed on to the next level. This concept is known as the 10% rule in ecology.

Uses sun's energy to create sugars

Back

Primary producer

Answer explanation

Primary producers, such as plants, algae, and some bacteria, use the sun’s energy to create sugars through the process of photosynthesis. These organisms form the base of the food chain by providing energy for other organisms.

Greatest biomass in food web: grass, mice, coyotes, hawks?

Back

Grass

Answer explanation

In any ecosystem, primary producers like grass typically have the greatest biomass. This is because they form the base of the food web and convert solar energy into biomass through photosynthesis. As energy is transferred up the trophic levels, from primary consumers (like mice and deer) to secondary consumers (like coyotes and hawks), a significant amount of energy is lost at each step, resulting in less biomass at higher trophic levels.
