Q4. Algae need nutrients like carbon, nitrogen, and phosphorus, among others, in order to grow. Could carbon ever limit algae growth? No. Carbon is abundant everywhere and so it can never be a limiting nutrient for algae. No. Algae are too small to ever require more carbon than what is available in the environment. Yes. Because carbon is needed by algae to grow, it has the potential to limit growth. Yes. Whenever phosphorus is added to a lake, algae grow and therefore use more carbon as well. Submit Q4.
