Bot GPT 3.5 A keystone species is a species that plays a crucial role in maintaining the structure and function of an ecosystem. These species have a disproportionately large impact on their environment relative to their abundance. If a keystone species were to be removed from the ecosystem, it could result in significant changes to the ecosystem, potentially leading to its collapse.
Keystone species are important to ecosystems because they help regulate the population sizes of other species, influence the distribution of other species, and contribute to overall ecosystem stability. They are often integral to food webs and can have cascading effects on other species if they were to disappear. By maintaining the balance and diversity of an ecosystem, keystone species help promote overall ecosystem health and resilience to environmental changes.
