How do primary consumers get energy?

Unlike producers, they cannot make their own food. To get energy, they eat plants or other animals, while some eat both. ... They eat primary producers—plants or algae—and nothing else. For example, a grasshopper living in the Everglades is a primary consumer.

Explanation:

As you can see, the primary consumer does not have all of the energy from the plant available to it. Only the green stored energy is available to the consumer. Thus, a primary consumer is going to be more efficient than a secondary consumer. A secondary consumer is going to be more efficient than a tertiary consumer.

Primary consumers are the herbivores and they come right after the producers, because they get their energy from eating plants.
