Which best describes the role of a primary consumer in a food web?
Soloha48 [4]

Answer:

Herbivore that feeds on producers

Explanation:

The producers are plants at the bottom of the food web. These are eaten by herbivores, that are the primary consumers.

Herbivore that feeds on producers  - this is correct

Herbivore that feeds on primary consumers  - primary consumers are animals and herbivores do not eat animals

Carnivore that feeds on primary consumers - this would be a secondary consumer
