Like most plants, the main way diatoms survive is through photosynthesis and water. Where do diatoms collect energy from? Diatoms have light-absorbing molecules (chlorophylls a and c) that collect energy from the sun and turn it into chemical energy through photosynthesis. Diatoms remove carbon dioxide (CO 2) from the …
A diatom (Neo-Latin diatoma) is any member of a large group comprising several genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world.
