Final answer:
Studying ecosystems aids in the conservation of endangered species by addressing the root causes of endangerment, indirectly protecting other species through ecosystem conservation, and promoting habitat preservation for the survival of endangered species.
Step-by-step explanation:
Studying ecosystems can help conserve endangered species in several ways. Firstly, focusing on whole ecosystems and landscapes rather than individual species can be more efficient and successful in conservation efforts, as it addresses the root causes of endangerment. Secondly, by protecting certain endangered species, other species that share the same ecosystem may also be indirectly protected. Lastly, studying ecosystems helps understand the importance of biodiversity and the need to preserve habitats, which is essential for the survival of endangered species.
