Question

Quizplus · Accepted Answer

Phototrophs rely on photons to excite electrons within their membranes. Heterotrophs cannot produce their own food and rely on other organisms for energy, while chemotrophs obtain energy from chemical reactions. Autotrophs produce their own food through photosynthesis or chemosynthesis. None of these except for phototrophs rely on photons to excite electrons within their membranes. Therefore, the best choice is 3 only.
