Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms’ activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek φῶς, phōs, "light", and σύνθεσις.

The tree of life is in constant flux as organisms are reclassified. Yet the philosophy of biology has struggled to define a species. A movement of pluralism has taken hold, leading philosophers to doubt or deny the existence of ‘species’ as a

MISCONCEPTION: Species are distinct natural entities, with a clear definition, that can be easily recognized by anyone.
