Answer the following question given this paragraph: 

Phototrophs are organisms that capture light energy and convert it to chemical energy inside their cell. Most phototrophs are the autotrophs that perform photosynthesis, which are also known as photoautotrophs. These organisms have the ability to fix carbon from carbon dioxide into organic compounds, such as glucose. Chemotrophs , on the other hand, do not get their energy from carbon. These are organisms that break down either organic or inorganic molecules to supply energy for the cell through chemosynthesis. Chemotrophs can be either autotrophic (chemoautotrophs) or heterotrophic (chemoheterotrophs). Chemoautotrophs derive their energy from chemical reactions, and synthesize all necessary organic compounds from carbon dioxide. Chemoheterotrophs are unable to fix carbon to form their own organic compounds. The various types of metabolisms are discussed in the Prokaryotes: Nutrition and Metabolism (Advanced) concept.


Q: Which organisms capture light energy and convert it to chemical energy inside their cell?


A:
phototrophs
