Phototrophs are organisms that obtain energy from light through a process called photon capture. They use the energy from light to power various metabolic processes within their cells. Examples of phototrophs include plants and algae, as plants grow by using energy from sunlight and algae can live in light-rich aquatic environments.

This article is about phototrophism, obtaining energy from light. For the tropism that governs
growth toward or away from a light source, see Phototropism.
Terrestrial and aquatic phototrophs: Plants grow on a fallen log floating in algae-rich water.
Phototrophs (Gr: φῶς, φωτός = light, τροϕή = nourishment) are the organisms that carry out
photon capture to acquire energy. They use the energy from light to carry out various cellular
metabolic processes.
