vetikatega

Vetikatega is a term that refers to algae in Estonian. Algae are a diverse group of aquatic organisms that are not plants, fungi, or animals. They range in size from single-celled organisms to large, complex seaweeds. Algae are found in almost every environment on Earth, from oceans and freshwater lakes to soil and even on other organisms.

There are many different types of algae, often categorized by their color. Green algae, red algae, and brown algae are common examples. These color differences are due to the presence of various photosynthetic pigments. Algae play a crucial role in ecosystems. They are primary producers, meaning they convert sunlight into energy through photosynthesis, forming the base of many aquatic food webs. They also produce a significant portion of the Earth's oxygen.

Humans utilize algae in various ways. They are a source of food for many cultures, particularly in Asia, where seaweed dishes are popular. Algae are also used in the production of agar, carrageenan, and alginates, which are common ingredients in food, cosmetics, and pharmaceuticals. Some algae are being researched for their potential as biofuels and for bioremediation, the process of using living organisms to clean up pollution.
