Explanation:
Multipotent stem cells are the one that develops from pluripotent stem cells during embryonic development. The multipotent stem cells are the stem cells which have specific functions. These cells develop into specific cell types to replace the older cells.
For example, keratinocytes are the multipotent cells of the skin that produce new skin cells. Spermatogonia are the multipotent cells present in testes so that they can form sperms.

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
