Question

Will fan and medal!
Sea otters are important predators of sea urchins, an animal that eats giant brown kelp in continental shelf zones where they form huge kelp beds. It was observed that the removal of sea otters from the west coast led to an increase in the sea urchin population. These sea urchins fed on the large kelp fronds, destroying the kelp beds that serve as an important source of food and protection for spawning fish. What role does the sea otter play in this case?

A. Dominant species B. Invasive species C. Keystone species

Answer 1

C. i think. because the sea otter is largely depended on.

Answer 2

I need this question to pass a test

Answer 3

well i f you think of it keystone species-is a species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically and invasive species is- is defined as an organism (plant, animal, fungus, or bacterium) that is not native and has negative effects on our economy, our environment, or our health. Not all introduced species are invasive. Invasive plants and animals are the second greatest threat to biodiversity after habitat loss.
and dominant species is- Ecological dominance is the degree to which a taxon is more numerous than its competitors in an ecological community, or makes up more of the biomass. Most ecological communities are defined by their dominant species.

Answer 4

so as you can see keystone is most likely the answer
