There are no specific criteria for things like the size or appearance of organisms to be keystone species. mixing stimulated by the migrants. The presence of starfish prevents from occurring various radical changes in the ecosystem like new invasive species populating the habitat, or leading to the over-growth of prey population than predators, or causing the over-growth of predator population than prey, or other various negative consequences. along the corridors they travel in order to meet their energetic requirements Robert realized that this was proof that one species can have a direct impact on the other animals inhabiting the ecosystem. Without the firecrown, the plants will struggle to reproduce, and without the plants, the firecrown loses its main food source.

As they are often the start of the food chain, losing keystone plants can cause effects across the food chain, affecting herbivores and the carnivores that eat them by providing less plant matter. This balanced seaweed population can in turn maintain the population count of other species that depend on the seaweeds for their sustainibility. And if that wasnt enough, sea otters only feed on bigger sea urchins, which in turn means that the small urchins are left alone, keeping the species and the cycle alive!
