Browsing: Diatoms

Diatoms are a major group of algae found in the oceans, waterways, and soils of the world. Known for their unique and beautifully intricate cell walls made of silica, which are often described as resembling glass houses, these microscopic organisms are key players in the Earth’s environment. Diatoms are important for their role in the carbon cycle as they are prolific photosynthesizers, producing a significant amount of the world’s oxygen. They also serve as a fundamental food source in aquatic ecosystems, supporting everything from microscopic animals to large marine mammals. The fossilized remains of diatoms, known as diatomaceous earth, are mined for various uses, including filtration, as abrasives, and as a stabilizing component of dynamite. Diatoms are used in research to study environmental conditions, including past climate patterns and present water quality. Their sensitivity to changes in water chemistry makes them excellent indicators of environmental conditions.
