What is euphoic zone?

The euphoric zone, often referred to in the context of marine environments, is the upper layer of a body of water where sunlight penetrates sufficiently to support photosynthesis. This zone typically extends to a depth of about 200 meters in the ocean, where light availability allows for the growth of phytoplankton, forming the basis of the aquatic food web. The euphoric zone is crucial for marine ecosystems as it contributes to oxygen production and carbon cycling.
