Detailed explanation-1: -Animals that eat only plants are called herbivores (or primary consumers). Animals that eat other animals are called carnivores. Carnivores that eat herbivores are called secondary consumers, and carnivores that eat other carnivores are called tertiary consumers.

Detailed explanation-2: -The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. The secondary consumers tend to be larger and fewer in number. This continues on, all the way up to the top of the food chain.

Detailed explanation-3: -These animals are called consumers because they consume something else to get their food. There are different types of consumers. An animal that eats producers, like plants or algae, is called an herbivore. Carnivores eat other consumers.

Detailed explanation-4: -The organisms that eat the primary consumers are called secondary consumers. Secondary consumers are generally meat-eaters (carnivores). The organisms that eat the secondary consumers are called tertiary consumers. These are carnivore-eating carnivores, like eagles or big fish.
