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.

Explanation:
Answer:
- prolonged exposure to high pressure zones
- mountain ranges
- cold oceanic currents
Explanation:
All deserts form because of prolonged period of lack of precipitation. That happens because of multiple reasons, with some of them being high pressure zones, mountain ranges, and cold oceanic currents. The high pressure zones are basically consisted of denser, lower air masses which do not allow the low pressure air masses to come in, thus stopping the rainfall. The mountain ranges are a natural barrier, and they manage to stop the wet air masses, so there's lot of rainfall on the windward side, but the leeward side will be very dry. The cold oceanic currents bring in colder and dry weather, with the air masses also being very dense, and while they manage to produce some moisture close to the ground, the rainfall is extremely rare.
