How does spirogyra eat food?

Spirogyra, a type of green filamentous algae, primarily obtains its nutrients through photosynthesis. It contains chloroplasts, which capture sunlight and convert carbon dioxide and water into glucose and oxygen. Additionally, spirogyra can absorb dissolved nutrients from its aquatic environment, such as nitrates and phosphates, through its cell walls. This dual method allows it to thrive in various freshwater habitats.
