Which of the following best explains why terrestrial trophic pyramids usually do not have levels higher than tertiary consumers?
Tertiary consumers are the largest organisms in an ecosystem and require the most space to survive.
Plants can only perform photosynthesis during the day, so tertiary consumers cannot get enough energy from consuming plants.
A large proportion of energy is lost as heat as it is transferred up the pyramid, so there is not enough energy available to support another level.
Tertiary consumers are often indicator species and are the first to be affected by environmental disturbances.

identifies what is "eaten" and what is the "eater" (Downward)
