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.

Herbivores themselves are consumed by carnivores, which are secondary consumers.

Sometimes, these carnivores can be consumed by top predators, like a shark, snake or eagle.

<u>Options and why they are right/wrong</u>

Carnivore that feeds on producers  - carnivores do not feed on producers

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
