Final answer:
A food animal is defined as an animal raised or hunted primarily for consumption, providing food products such as milk, eggs, and meat.
Step-by-step explanation:
The definition of a food animal is A. Provide food products. Food animals are species of animals that humans raise or hunt primarily for consumption. These animals, such as cows, pigs, chickens, and fish, are sources of a variety of food products, including milk, eggs, and meat, which are rich in essential nutrients like amino acids and have high nutritional values.
Contrarily, pets (B), items made from animal parts (C), and animals that assist people, like service dogs (D), do not fit the definition of food animals, although there can be cultural overlaps in how different societies classify certain animals.
