Algae are some of the most important organisms on the planet, but they are largely ignored and viewed as gross or unappealing. However, algae are responsible for playing a key role in providing life in a variety of areas, including coral reefs and in the tundra where lichen (an association of algae and fungi) is one of the few organisms that can exist.

Algae provide food for other organisms, and are also used in everything from fertilizers to toothpaste, in addition to their role in oxygen production.

While algae isn’t viewed as particularly appealing, it can work great in photographs, because of the bright colors that contrast against everything from rocks to water:
