Geographical and environmental impacts on symbiotic relationships between anemone and algae

Corals and anemones form a symbiotic partnership with photosynthetic algae based on an exchange of nutrients: the host receives sugar from the algae, the algae receives nutrients and consistent exposure to sunlight from the host. This relationship can break down under stressful conditions, a phenomenon known as 'bleaching,' which, in the case of tropical corals, can quickly lead to the death of the host. Bleaching resistance can arise if a local population consistently encounters and adapts to warmer conditions.
