Final answer:
An eukaryotic organism that can make its own food is called an autotroph.
Step-by-step explanation:
An eukaryotic organism that can make its own food is called an autotroph. Autotrophs are able to produce organic molecules, such as glucose, through processes like photosynthesis or chemosynthesis, using energy from the environment.
Autotrophs are essential in the food chain as they form the basis for energy production. Examples of autotrophs include plants, algae, and some bacteria.
Autotrophs are the opposite of heterotrophs, which cannot make their own food and must rely on consuming other organisms for energy.
