Identify an example of organisms that do NOT belong to the third trophic level.

Correct option is D

Cows
 Producers always occupy the first trophic level of a food chain. The primary consumers or the herbivores occupy the second trophic level. Carnivores or the secondary consumers occupy the third trophic level and the predators that consume the primary consumers occupy the fourth trophic level.
 Cows are herbivores, which means they eat plants. This places them in the second trophic level of the food chain. The third trophic level is occupied by carnivores, which eat other animals. Fish, wolves, and birds can all be carnivores, depending on their diet.
Here is an example of a food chain that includes cows:
 Grass --> Cow --> Human
In this food chain, the grass is the producer, the cow is the primary consumer, and the human is the secondary consumer. The cow is not in the third trophic level because it does not eat other animals.
