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.
A scientific theory is an explanation of the natural world on the basis of facts which have been repeatedly confirmed by experiments and observations. <span>Scientific laws are rules that explain observations through either text or mathematic forms. These laws suggest cause and effect from observations and must be repeatable.

Therefore this would be a fact-supported scientific theory as it is an explanation based upon repeatedly confirmed experiments and observations, unlike Scientific law, which would be mathematical.
