The correct answer is: A.Make their own food.

Autotrophic organisms, such as plants, algae, and some bacteria, can produce their own food through processes like photosynthesis or chemosynthesis. They use energy from sunlight or chemical reactions to convert inorganic substances (like carbon dioxide and water) into organic compounds (like glucose). This ability distinguishes them from heterotrophic organisms, which cannot make their own food and must obtain energy by consuming other organisms (plants, animals, or other heterotrophs).

Here’s why the other options are not correct:

B.Have a nucleus: Both autotrophic and heterotrophic organisms can have a nucleus. This is characteristic of eukaryotic organisms, which include both autotrophs (like ...
