biological classification

Diatoms are a type of microscopic algae that are characterized by their unique cell walls made of silica. They are crucial to aquatic ecosystems and play a significant role in the Earth's carbon cycle. Found in both freshwater and marine environments, diatoms are known for their yellow-brown pigments, which enable them to perform photosynthesis. They form intricate and beautiful patterns, making them a topic of interest in both science and art. Diatoms contribute substantially to the productivity of oceans and are a primary food source for various marine life forms.
