What is the ecological benefits that the presence of sponges may have on aquatic systems?

Sponges play a crucial role in aquatic ecosystems by filtering water, which helps to improve water clarity and quality by removing suspended particles and nutrients. This filtration process can reduce harmful algal blooms and support the overall health of the ecosystem. Additionally, sponges provide habitat and refuge for various marine organisms, contributing to biodiversity. Their ability to recycle nutrients also enhances the productivity of surrounding environments.
