Show the following as a food chain: omnivore, autotroph, herbivore
Thepotemich [5.8K]

omnivore⇒herbivore⇒autotroph

this is because an autotroph makes its own food (photosynthesis) so it doesn't have the need to eat other organisms. Herbivores eat only plans (remember this with the word herb is a type of plant) and an omnivore will eat either meat or plants so it can eat either of the things below it.
