As many as 9000 species of algae are spread across the worlds oceans, some can be as much as 30 metres across while others are just a slippery scum over rocks.
Algae grows wherever there is enough light and life supporting conditions.
Algae has it's own life support system and doesn't feed as other animals do it "makes" its own food "Glucose" which it feeds on.
This is achieved with the help of "Chlorophyll". Chlorophyll is a pigment that takes in sunlight to generate energy for food production. Then carbon dioxide is taken in from the water to make glucose.
Algae support a huge number of marine life both for food and as a home. Ref: https://www.sealifebase.ca/summary/Gibsmithia-hawaiiensis.html
