What does algae?

Answer 1

What algae will consume depends on the particular species of algae, whether autotrophic, heterotrophic, or mixotrophic, and the conditions it is in. Photoautotrophic algae (plant-like algae) mostly need sunlight, Nitrogen, Potassium, and Phosphorus as well as water and CO2. Other species are able to survive without sunlight and others feed on bacteria and sugars instead of making their own sugars. Sometimes even photoautotrophic and heterotrophic algae if in lack of O2, they can no longer respirate so they go into anaerobic respiration and ferment.
