Keystone Keepers

This passage defines keystone species, explaining their disproportionate impact on ecosystems. It discusses examples like the sea otter and wolves, which maintain ecological balance by controlling prey populations. Without keystone species, ecosystems can face issues such as overpopulation of certain species and habitat degradation. The passage emphasizes the critical role of these species in preserving biodiversity.

Reading about keystone species enhances students’ scientific vocabulary by introducing them to ecological concepts like “keystone species” and “biodiversity”. It improves comprehension by presenting real-world examples that illustrate the species’ impact on ecosystems. The passage encourages critical thinking as students consider the consequences of losing these species. Additionally, it helps students practice identifying cause-and-effect relationships.
