Symbiosis

Symbiotic relationships are when one organism helps another organism. One example of a symbiotic relationship is when a bark beetle eats the bark of an oak tree. The beetle gets a meal and the tree gets nothing. Also when bacteria breaks down a red fox the fox is decomposed and the bacteria gets a meal. When a red squirrel is eaten by a fox the fox gets a meal and the squirrel gets nothing.

What type of symbiotic relationship does the bark beetle have with the oak tree?

Bacteria breaking down the red fox sounds like the end of a food chain. Is a part of a food chain or is it a symbiotic relationship?
