What is the ecological role of Ulva?

Ulva, commonly known as sea lettuce, plays a vital ecological role in marine ecosystems. It serves as a primary producer, converting sunlight into energy through photosynthesis, which supports various marine food webs. Additionally, Ulva provides habitat and shelter for a range of marine organisms, including small fish and invertebrates. Furthermore, it contributes to nutrient cycling and can help mitigate excess nutrients in coastal waters, promoting overall ecosystem health.
