Pollution
This is acid rain. When CO2 gets into the water in the clouds, the rain that falls is acid rain. This acid rain kills many plants, so try to help stop forest fires.
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.
