Detailed explanation-2: -Producers, who make their own food using photosynthesis or chemosynthesis, make up the bottom of the trophic pyramid. Primary consumers, mostly herbivores, exist at the next level, and secondary and tertiary consumers, omnivores and carnivores, follow.

Detailed explanation-3: -A producer is an organism which produces its own food through photosynthesis. 3. A consumer is an organism which does not make its own food but must get its energy from eating a plant or animal.
