zooxanthellae

Zooxanthellae are tiny, photosynthetic algae that live inside the tissues of certain marine animals, such as corals and some sea anemones. These algae play a crucial role in the health of their host organisms by providing them with energy through photosynthesis, which is the process of converting sunlight into food. In return, the host provides zooxanthellae with a protected environment and the nutrients they need to thrive. This symbiotic relationship enables coral reefs to flourish, supporting diverse marine ecosystems. However, changes in environmental conditions can disrupt this balance, leading to coral bleaching and other ecological challenges.
