Impact of Keystone Species on Ecosystems

Easy Reading Comprehension Passage-based Questions

In the heart of an ancient forest, a diverse range of flora and fauna coexist, creating a rich tapestry of biodiversity. Scientists have long studied these ecosystems to understand the intricate relationships among species. Recent research highlights the critical role of keystone species, which are essential for maintaining the structure of the ecological community. For example, the removal of a single keystone species can lead to dramatic changes in the habitat and the ensuing population declines of other species.

This research underscores the importance of conservation efforts aimed at protecting these vital species. Without them, the entire ecosystem may be compromised, leading to a cascade of extinctions and loss of biodiversity.
