Photoautotrophs use ______.

Question

KollegeApply · Accepted Answer

Photoautotrophs use light as an energy source and can use water or hydrogen sulphide as a source of electrons for producing organic compounds. Explanation: Photoautotrophs capture light energy to produce organic molecules through photosynthesis. Some photoautotrophs, such as cyanobacteria, use water as the electron donor, releasing oxygen (oxygenic photosynthesis), while others, like certain sulfur bacteria, use hydrogen sulphide as the electron donor (anoxygenic photosynthesis).
