Question

how do plants and other autotrophs get their energy?

Explanation:

Plants and other autotrophs obtain energy through photosynthesis. They use sunlight, carbon dioxide, and water to produce glucose (a form of stored energy) and oxygen. This process occurs in the chloroplasts of plant cells. Another way some autotrophs (like certain bacteria) can get energy is through chemosynthesis. In chemosynthesis, autotrophs use chemical energy (from inorganic compounds like hydrogen sulfide) instead of light energy to make organic molecules. But for most plants, photosynthesis is the primary energy - obtaining mechanism.

Answer:

Plants and most autotrophs get their energy mainly through photosynthesis (using sunlight, \(CO_2\), and \(H_2O\) to make glucose). Some autotrophs can also use chemosynthesis (using chemical energy from inorganic compounds).
