What impact do healthy coral reefs have on biodiversity?

Healthy coral reefs are vital ecosystems that support a diverse range of marine species. This immense biodiversity is largely due to the complex structures and habitats that coral reefs create. These structures provide shelter and breeding grounds for various marine life, including fish, invertebrates, and other organisms. The presence of corals allows for a greater variety of species to coexist, as different niches are formed in the reef environment.

In addition to providing physical habitats, coral reefs also offer essential resources such as food and protection for many marine organisms. The interdependence among species within these ecosystems contributes to overall ecological balance and resilience. Diverse coral reef communities are more likely to recover from disturbances such as storms or temperature changes, thus maintaining their health and the myriad of life forms that depend on them.

Other options do not accurately describe the impact of healthy coral reefs on biodiversity. For instance, the idea that they decrease overall marine biodiversity contradicts established ecological understanding. Similarly, while coral reefs do support fish populations, they encompass a broader range of species and are not limited to just fish. Lastly, the statement about leading to the extinction of some coral species overlooks the fact that healthy reefs actually promote the survival of various species by providing diverse habitats.
