What does asterionella eat?

Asterionella, a genus of freshwater diatoms, primarily feeds on dissolved organic matter and nutrients in the water, such as silica, nitrogen, and phosphorus. They utilize photosynthesis to produce energy, converting sunlight into chemical energy while absorbing carbon dioxide and releasing oxygen. Their role in aquatic ecosystems is crucial as they contribute to primary production, forming the base of the food web for various aquatic organisms.
