Does green algae live in the ocean?

Green algae can be found in a wide range of habitats, including the ocean. They are not as abundant in the open ocean as they are in coastal areas and estuaries, where they can thrive in shallower waters with access to sunlight. Green algae are photosynthetic, meaning they use sunlight to convert carbon dioxide into organic matter. They can form dense mats or blooms in nutrient-rich waters, particularly during warm, sunny weather. Some species of green algae, such as Ulva and Enteromorpha, are commonly found in the marine environment and play important roles in marine ecosystems.
