What are three examples of keystone species Why are they so important?
A keystone species is an organism that helps define an entire ecosystem. By keeping populations of mussels and barnacles in check, this sea star helps ensure healthy populations of seaweeds and the communities that feed on them—sea urchins, sea snails, limpets, and bivalves.
What are keystone species?
A keystone species is a plant, animal, fungi, or even bacteria that has a disproportionately large impact on their ecosystem. They play an important role in their natural environments as their impact on other species can reshape entire ecosystems.
Are dolphins a keystone species?
Dolphins are a critically important keystone species, meaning that a healthy population of river dolphins indicates a healthy and functioning river ecosystem at large. As predators, dolphins help maintain fish populations in the river.
Is a shark a keystone species?
