Photoautotrophic organisms are sometimes referred to as holophytic. Learn. Narrowly defined, photoautotrophy is a nutritional status where living organisms grow without any additional exogenous organic components as nutrients. Phototrophs (Gr: φῶς, φωτός = light, τροϕή = nourishment) are organisms that carry out photon capture to produce complex organic compounds (such as carbohydrates) and acquire energy.
