Question

Why are plants called autotrophs?

• A. Because they depend on other organisms for energy and all nourishment.
• B. Because they capture energy from sunlight and give it to animals to make their food.
• C. Because they derive their energy directly from the sun to produce food for themselves.
• D. Because they do not need sunlight for energy.

Answer 1

The correct option is C

Because they derive their energy directly from the sun to produce food for themselves.

Plants are called autotrophs because they utilise sun's energy and simple compounds like carbon dioxide and water to make their own food (glucose). They are not dependent on other organisms for energy and instead directly obtain it from sunlight and other molecules present in the environment.
