The significance of species diversity lies in the fact that:
C. Species interact with their environment and perform certain functions.
Here's why this is the correct answer:
1. **Interactions with the environment:** Species diversity is important because different species interact with their surroundings in unique ways. For example, some species help in pollination, nutrient cycling, or pest control, contributing to the overall health and balance of ecosystems.
2. **Performing functions:** Each species has a specific role or function within its ecosystem. For instance, predators help control prey populations, while decomposers break down organic matter. The presence of a variety of species ensures that all necessary ecological functions are carried out efficiently.
By maintaining a diverse array of species, ecosystems become more resilient to changes and disturbances, promoting stability and sustainability in the long term.
