A student drew the model above to demonstrate the amount of energy at each trophic level in an ecosystem. Is the model accurate?

• The student's model is accurate. The model is wider at the top indicating there is more energy available at trophic level 3 than trophic level 2.

• The student's model is accurate. The model is wider at the top indicating carnivores have more energy available to them than herbivores.

• The student's model is inaccurate. The model should be wider at the bottom than at the top, reversed with carnivores at the bottom having the most energy.

• The student's model is inaccurate. The model should be wider at the bottom than at the top demonstrating producers have the most energy available to them.
