24. Trophic Levels of The Food Chain
(the position an organism holds in a food chain)
Level 1 – Producers (organisms that make their
own food)
Level 2 – Primary Consumers (herbivores that
eat plants)
Level 3 – Secondary Consumers (carnivores that
eat herbivores)
Level 4 – Tertiary Consumers (carnivores or
omnivores that eat other carnivores)
