A team of ecologists observed feeding patterns of several populations in the desert. Which of the following best explains the difference in the amount of available energy in the trophic levels of the desert ecosystem?

• There is less energy in the producers because they are at the bottom.

• There is more energy in the producers because they provide energy for all the consumers in the ecosystem.

• There is more energy available in the tertiary consumers because they need the energy to hunt.

• There is more energy in the level containing the top predators because they are larger in size.
