2. For example, certain fungi live in the roots of trees. The tree provides nutrients to the fungus and, in return, receives help from it to take up water and nutrients from the soil. This association is very important for the tree.
3. In organisms called lichens, a chlorophyll-containing partner, which is an algae and a fungus live together.
