Coral Reef Ecology is a captivating field that explores the intricate and diverse ecosystems found within coral reefs. These vibrant marine ecosystems are teeming with life, hosting an incredible variety of species that contribute to their health and stability. The coral ecosystem itself is a complex web of interactions between corals, fish, invertebrates, and algae, all of which play a crucial role in maintaining the balance of these underwater habitats.

The ecosystem in coral reefs is highly sensitive to environmental changes, making it an important indicator of ocean health. Coral reefs thrive in clear, shallow waters where sunlight can penetrate, supporting the photosynthetic algae, known as zooxanthellae, that live within the coral tissues. These algae provide essential nutrients to the corals through photosynthesis, enabling them to build their calcium carbonate skeletons, which form the structure of the reef.

The marine ecosystem coral reefs support is not only biodiverse but also economically significant, providing resources and services such as fisheries, tourism, and coastal protection. However, coral reefs are under threat from climate change, pollution, and overfishing, which can disrupt the delicate balance of these ecosystems.
