Life   Algae

Algae are mainly found in marine or freshwater environments but also occupy such extreme environments as deserts, boiling springs, ice, and snow. Algae survive by capturing light energy which is used to convert inorganic substances into simple sugars, this process is commonly known as Photosynthesis. As a by-product of photosynthesis, Algae produce oxygen which other aquatic life uses. Algae can be found in a variety of forms ranging from single-celled to complex multicellular forms, such as the Kelp which grow to be over sixty meters in length. Algae are vital in many food chains acting as the primary producer of organic matter. Algae are important to humans in the form of food and medicine. Algae are also important in the make up of coral reefs,
