diatoms

Diatoms are tiny, single-celled algae found in aquatic environments, including oceans, lakes, and rivers. They are distinguished by their beautiful, intricate silica-based cell walls called frustules, which have detailed patterns and structures. Diatoms play a crucial role in ecosystems by producing a significant portion of the world's oxygen through photosynthesis and forming the foundational food source for many aquatic organisms. Their silica shells also contribute to sediment formation when they die. Due to their abundance and productivity, diatoms are vital for maintaining healthy aquatic ecosystems and influencing global carbon cycles.
