The digram is the pyramid

tertiary consumers: known as apex predators are mostly CARNIVORES but sometimes can be omnivores

secondary: has some carnivores but i would say OMNIVORES

primary: HERBIVORES

primary producer: AUTOTROPH. like grass

heterotrophs: an organism deriving its nutritional requirements from complex organic substances. so like a grass hopper or toad/frog

Thats bot a question
