TUDOMÁNY ÉS TECHNIKA: Understanding coral reefs: a delicate underwater ecosystem

Coral reefs, often referred to as the “rainforests of the sea,” are a vital part of our planet’s ecosystem. Let’s explore their intricate biology, importance, threats, and efforts for their conservation. The fascinating life of coral reefs Coral reefs are complex and fascinating ecosystems that support a diverse range of marine life. They are made up of colonies of tiny organisms called corals or polyps, which secrete a hard limestone skeleton that forms the reef’s structure. These polyps have a symbiotic relationship with algae called zooxanthellae, which live inside the coral tissues. Through photosynthesis, the algae provide the coral with nutrients, including oxygen, glucose, and amino acids, which enable the coral to grow and survive. In return, the coral provides the algae with a protected environment and access to sunlight. The algae also give the coral its vibrant colours, which can range from bright greens and yellows to deep blues and purples. However, this symbiotic relationship is delicate and sensitive to changes in temperature and light. When corals are exposed to negative conditions, such as high water temperatures or pollution, they may expel the algae, causing the coral to turn white, a process known as coral bleaching. While corals can […]
