Understanding Biodiversity and Its Impact

Easy Reading Comprehension Sentence-level Questions

The importance of biodiversity is a fundamental topic in ecology. Biodiversity, or the variety of life in a particular habitat or ecosystem, provides numerous benefits.

For instance, it enhances ecosystem productivity, where each species, no matter how small, has an important role to play. A well-balanced ecosystem can support a greater number of plant species, which in turn support a higher variety of animals. Moreover, biodiversity contributes to ecosystem services such as pollination, water purification, and climate regulation.

However, human activities, such as deforestation, pollution, and climate change, threaten these ecosystems. It is crucial to understand the implications of losing biodiversity—both for the health of our planet and for human survival.
