Final answer:
Autotrophs convert energy from sunlight or inorganic compounds into energy stored in the carbon-carbon bonds of carbohydrates through the processes of photosynthesis and chemosynthesis.
Step-by-step explanation:
The statement is true. Autotrophs, such as plants, use energy from sunlight to convert inorganic compounds into energy stored in carbohydrates. This process is called photosynthesis. Other autotrophs, like certain bacteria, use energy from chemicals to perform a similar process called chemosynthesis. Both photosynthesis and chemosynthesis involve the conversion of energy into chemical bonds in carbohydrates.
