Describe each of the two ways in which autotrophs derive energy; what are each of these autotrophs called?
a. Autotrophs derive energy through photosynthesis, using sunlight to convert carbon dioxide and water into glucose. These autotrophs are called photoautotrophs.
b. Autotrophs can also derive energy through chemosynthesis, using chemical reactions to produce organic compounds from inorganic substances. These autotrophs are called chemoautotrophs.
