Answer:

The answer is C)

Explanation:

The predators were unable to keep the population of the mussels down. The mussels took more area of the rock. Other species that needed space did not return to the tidal pool. Otters can also be keystone species as they eat urchins. By doing so, they prevent the sea urchins form eating all the kelp plants and removing the entire habitat for many other species. The Keystone Species theory shows that this impact of few predators, that made up a minor amount of the total species, could have such a high impact on the ecosystem.

nika2105 [10]

Answer:

The map shows the locations of divergent plate boundaries.

Explanation:

There are three main types of plate boundaries, divergent, convergent, and transform plate boundaries. They are defined in accordance with the interaction that the plates have between each other. At divergent boundaries the plates move away from each other, at convergent boundaries, they move toward each other, and at transform boundaries, they slide past each other.

On this map, we have marked the locations of the divergent plate boundaries. We have the divergent boundaries between the Eurasian and Africa plates on one side and North American and South American on the other side, between the Pacific plate and Nazca plate, and between the Pacific and Nazca on one side and Cocos plate on the other Last but not least, there is the divergent plate boundary between the Antarctic plate on one side and the Australian, African, and South American plates on the other sides.
