The correct answer is option C, that is, it makes its own food.
The autotrophs accumulate chemical energy in the form of carbohydrates, which they produce themselves. Food is the chemical energy accumulated in organic molecules. The majority of autotrophs convert sunlight to produce food, by the process known as photosynthesis.
Only three species groups, that is, plants, some bacteria, and algae possess the tendency to perform the process of photosynthesis. The autotrophs are also known as producers, they start the food chains and feed all the forms of life.
C.It makes its own food.
An autotroph is an organism that can create its own food using light, water, carbon dioxide, or other substances. Because they can generate their own food, they are seldom called producers. Most autotrophs practice a process called photosynthesis to manufacture their food. In photosynthesis, autotrophs utilize energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a kind of carbohydrate. The glucose supplies energy to plants. Plants also use glucose to produce cellulose, a substance they use to develop and manufacture cell walls.
