Any relationship in which two different species use each other to live. This relationship could be beneficial to only one and harmless to the other. It could be mutually beneficial to both. It could also be beneficial to one and harmful to the other. What group do these relationships belong to?

Ecology

Give two differences between autotrophs and heterotrophs
Autotrophs: make their own food, can use sunlight to make food, use carbon dioxide to begin photosynthesis...
Heterotrophs: must consume a producer/autotroph or an animal that has consumed a producer/autotroph to obtain energy, gives off carbon dioxide as a waste product and uses oxygen for respiration...

All energy on Earth must go through this group of organisms before entering a different trophic level.
