How do autogrophs obtainanergy?

Answer 1

Autotrophs obtain energy primarily through the process of photosynthesis or chemosynthesis. In photosynthesis, they convert light energy from the sun into chemical energy by transforming carbon dioxide and water into glucose and oxygen, using chlorophyll in their cells. Chemosynthetic autotrophs, on the other hand, obtain energy by oxidizing inorganic substances, such as hydrogen sulfide or ammonia, to produce organic compounds. Both processes enable autotrophs to serve as primary producers in ecosystems, forming the base of the food chain.
