Plants are called producers because they are able to use light energy from the sun to produce food (sugar) from carbon dioxide and water. Animals cannot make their own food so they must eat plants and/or other animals. They are called consumers. There are three groups of consumers. 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. Animals and people who eat both animals and plants are called omnivores. Then there are decomposers (bacteria, fungi, and even some worms), which feed on decaying matter.
The living organisms that eat the producers are then considered to be the primary consumers, similarly to how the first person to buy a car is the primary consumer of that particular car. The primary consumers now have energy, and other organisms that are called secondary consumers can eat them. Secondary consumers are those organisms whose main food source is primary consumers. This is similar to you as the second consumer of the car. Even the secondary consumers have energy to pass on and can then be consumed by the tertiary consumer. These consumers are those who feed mostly on secondary consumers. As you may have guessed at this point, the tertiary consumer is just like the person that may buy the used car from you. Now that you know what a primary consumer is, let's look at some examples.
