A rat feeding on a potato is an example of a primary consumer.
The three levels of consumers found in an ecological food chain are primary, secondary, and tertiary consumers. Each consumer is critical in maintaining a healthy population of lower trophic levels.
- Primary consumers are the animals that feed on primary producers.
- They make the second tropical level of the energy pyramid and are consumed by secondary and tertiary consumers.
- Ruminants, herbivorous birds, zooplankton, etc. are some examples of primary consumers.
