Final answer:
Photosynthetic autotrophs are producers that use the sun to make usable chemical energy.
Step-by-step explanation:
True. Photosynthetic autotrophs, such as plants, algae, and some bacteria, use sunlight as an energy source to convert carbon dioxide and water into glucose and oxygen through the process of photosynthesis. This glucose is then used to produce usable chemical energy for the organisms. For example, plants use this stored energy to carry out cellular respiration and perform various functions.
