Question

which of the following is an example of a quaternary consumer? *
a plant
a herbivorous insect
a carnivorous mammal
a decomposer

Explanation:

Quaternary consumers are at the top - most trophic level in a food chain. They are apex predators. A plant is a producer (1st trophic level). A herbivorous insect is a primary consumer (2nd trophic level). A decomposer breaks down dead organisms and is not part of the typical consumer levels. A carnivorous mammal can be a secondary, tertiary, or in some cases a quaternary consumer. Among the options, a carnivorous mammal is the most likely to be a quaternary consumer as it can be an apex predator in some ecosystems.

Answer:

C. A carnivorous mammal
