Nutrias marinas

The video discusses the importance of kelp forests as habitats for marine life and the threat posed by sea urchins. Otters, as omnivores, play a crucial role in the marine food web by controlling sea urchin populations. This balance is vital for the survival of various species, making otters a keystone species in the ecosystem.

What would be the consequence for marine life if kelp forests were destroyed?

Explain the concept of a keystone species and provide an example from the text.
