Final answer:
Keystone species are critical to the survival of an ecosystem.
Explanation:
The species that are critical to the survival of an ecosystem are known as keystone species. These species have a disproportionately large effect on their environment compared to their abundance. They play a crucial role in maintaining the structure and function of the ecosystem.
For example, in a marine ecosystem, the sea otter is considered a keystone species. The presence of sea otters controls the population of sea urchins, which feed on kelp. Without sea otters, the sea urchin population would increase rapidly, leading to the overconsumption of kelp and the collapse of the entire ecosystem.
Therefore, keystone species are vital for maintaining biodiversity, regulating populations, and preserving the overall health and stability of an ecosystem.
