Zooxanthellae, a type of photosynthetic algae, receives energy from the sun through the process of photosynthesis. During this process, the zooxanthellae captures sunlight and converts it into chemical energy in the form of organic compounds, primarily glucose. The exact amount of energy acquired from the sun by zooxanthellae can vary depending on factors such as light intensity, water depth, and the health of the coral host they reside in. Generally, it is estimated that zooxanthellae can receive around 100-200 watts of energy per square meter of coral reef surface area.
