Filamentous algae can typically be found where?

Filamentous algae are known for their adaptability and can thrive in a variety of aquatic environments. They are commonly found in both fresh and saltwater settings, as they can grow in nutrient-rich as well as nutrient-poor waters. Their presence is not restricted to stagnant waters; they can also be found in flowing water bodies. Furthermore, filamentous algae do not solely inhabit polluted waters—while they may proliferate in nutrient-enriched conditions often associated with pollution, they can also thrive in relatively clean waters. Therefore, the answer accurately reflects the broad ecological niches these algae occupy.
