'''Algae''' is the term for several groups of simple living organisms that capture [[light]] and process it through [[photosynthesis]] to create the energy they need to live and grow.  They can occur in most habitats but are usually found in damp places or bodies of water.  [[Phytoplankton]], living in oceans and lakes is the basis for most marine food chains.  Some are used as human food or harvested for useful substances such as agar or fertilizer.
