Final answer:
Healthy ecosystems rely on a A. balance of abiotic and biotic factors, which interact to maintain the system's health and functionality. Coral reefs and warm oceans play a role in particular ecosystems but are not universally necessary for all ecosystems.
Step-by-step explanation:
Healthy ecosystems depend on a balance of abiotic and biotic factors. Abiotic factors are the non-living chemical and physical components of the environment, such as light, temperature, and water movement. Biotic factors include all the living components, such as plants, animals, and microorganisms. Together, these factors interact and contribute to the overall health and functioning of an ecosystem.
While coral reefs and components such as zooxanthellae and factors like warm oceans do play roles in specific ecosystems, they are not universally necessary for the health of all ecosystems. It's the balance of abiotic and biotic factors that is crucial across diverse ecosystems, whether they are terrestrial or aquatic, such as marine biomes. Marine biomes, for instance, have distinctive abiotic factors like salt content and water depth that shape their communities, as well as biotic components like corals and fish that maintain the ecosystem's balance and health.
