Organisms that eat plants
Primary consumers
Organisms that make their own food through photosynthesis
Producers

Protein
Animals that eat the remains of already dead animals and plants
Scavengers
Organisms that eat primary consumers but may also eat producers
Secondary consumers
A permanent close relationship between two organisms that benefits at least one of them
Symbiosis
Organisms that eat secondary consumers but may also eat primary consumers and producers
Tertiary consumers
