Which of the following best explains why terrestrial trophic pyramids usually do not have levels higher than tertiary consumers?ResponsesTertiary consumers are the largest organisms in an ecosystem and require the most space to survive.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.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.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.

Why is there a decrease in available energy at each successive trophic level in an energy pyramid?*1 pointOrganisms release energy as heat during metabolic processesOrganisms store energy in their bodies as biomassOrganisms use energy for growth and reproductionOrganisms transfer energy to predators through consumption

In the pyramid of energy, organisms that obtain their energy from only eating primary producers are calledMultiple Choicesecondary producers.tertiary consumers.secondary consumers.tertiary producers.primary consumers.

Terrestrial ecosystems rarely support trophic levels higher than tertiary consumers. Aquatic ecosystems, on the other hand often support numerous quaternary consumers like tiger sharks and marlins. Which of the following best explains why aquatic ecosystems can support higher trophic levels beyond the tertiary level?

Select all the correct answers.In an aquatic ecosystem, the fishing of a particular fish species increased. This fish species is a secondary consumer in an energy pyramid. The fishing of the species led to a decrease in its population. In which two ways will this affect the food web? The higher levels in the pyramid will receive more energy. The higher levels in the pyramid will receive less energy. The lower levels in the pyramid will have less predation. The higher levels in the pyramid will receive no energy at all. The lower levels in the pyramid will receive less energy.

A trophic level refers to*1 pointThe number of animals in the ecosystemOnly the plants and does not include animalsThe position the organism has in a food pyramid or food webThe ability of an organism to survive in a new ecosystem
