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.

The higher the food chain, the lower the food. The food chain(trophic pyramid) is shaped like a pyramid for a reason: a great amount of energy is lost at each trophic level, and so there is only enough food for higher trophic level organisms hence the pyramid becomes narrower towards the top and peaks at the tertiary consumers. The herbivores which are primary consumers benefit more or have more food and have a much broader base than the former since they are closer to the producers-plants.

The option that best explains the reason why the terrestrial trophic pyramids usually do not have levels higher than tertiary consumers is that 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.

It should be noted that a terrestrial pyramid has more biomass in plants. The energy pyramids depict the flow of energy in the trophic levels.

The highest level in a terrestrial trophic pyramid is the tertiary consumers. The reason for this is the loss of energy when heat is transferred into the pyramid.

In conclusion, the correct option is C.
