Ecologists study the interaction of organisms at five different levels. Which best places the levels in order from smallest to largest?

• population→ ecosystem→ organism→ community→ biome

• community→ organism→ population→ biome→ ecosystem

Which of the following best describes how the chemical energy travels up the food pyramid?

• Chemical energy is used by each of the organisms in the food pyramid, resulting in less energy as it moves up the pyramid.

• Chemical energy is made by each of the organisms in the food pyramid, resulting in more energy as it moves up the pyramid.

• Chemical energy is not needed by the organisms in the food pyramid, resulting in equal amounts of energy throughout the food pyramid.

• Chemical energy is used by producers but created by consumers, resulting in fluctuations in the amounts of energy throughout the food pyramid.
