Anabaena

Anabaena is a type of filamentous, photosynthetic bacteria found mainly in freshwater environments. It plays a key role in ecosystems by converting sunlight into energy through photosynthesis, similar to plants. Anabaena can fix atmospheric nitrogen, turning it into a form usable by living organisms, which makes it important for nutrient cycling. Sometimes, it forms visible filamentous clusters called blooms, especially in nutrient-rich waters. While beneficial for natural ecosystems, these blooms can sometimes produce toxins affecting water quality and aquatic life. Overall, Anabaena is a vital component of aquatic ecosystems, contributing to oxygen production and nutrient dynamics.
