An organism that eats animals to gain energy is a

• A. Carnivore
• B. Predator
• C. Omnivore
• D. Prey

Answer: (A)

The main idea is how organisms obtain energy from their food. An animal that gets its energy by eating other animals is a carnivore. Carnivores rely on meat for their energy and nutrients, and they often have adaptations for catching and processing animal prey.

This is distinct from being an omnivore, which means eating both plants and animals, not just meat. It’s also different from being prey, which refers to the role of an organism being eaten by others, not what it eats. While many carnivores are also predators—organisms that hunt prey—the key label here is diet: meat-eating animals are carnivores.
