Coral reef ecosystems have certain adaptive mechanisms to cope with environmental changes. For instance, some corals can produce a sunblock-like mucus layer to protect against increased UV radiation. Others might change their nutritional sources, relying more on zooplankton when their symbiotic algae are less productive. Some species of coral and fish can even adjust their reproductive timing based on environmental cues. However, it's essential to note that the rapid pace of current environmental changes, driven by human activities, often outstrips the adaptive capabilities of many coral reef species.
