Question

If these organisms were arranged in a food pyramid, which organism would have the least amount of total energy available?
Coyote
Insect
Lizard
Shrub

Answer 1

Answer;

Coyote

Explanation;

• Energy in a pyramid decreases from the lowest trophic level to the highest trophic level.
• Producers which are plants occupy the lowest trophic level and have the highest amount of energy as they use energy from the sun to make their own chemical energy that flows an ecosystem through the trophic levels.
• Energy flows from one trophic level to another when an organism eats another. Only ten percent (10%) of energy is passed to the next energy level, the rest is lost in form heat energy.
• Therefore, since coyote is a carnivore and occupies the highest trophic level among the choices given then it will have the least amount of energy.

Answer 2

Lizard will have the least energy.

A food pyramid shows the energy relationship between organisms. The organisms that are consumers occur higher in the pyramid while producers occur lower in the pyramid.

Recall that organisms that are higher in the pyramid have less energy. Hence, Lizard will have the least energy.
