Two examples of symbiotic relationships between species in Temperate Woodlands?

Mycorrhizas, or "fungus root" are fungi that live in a
close symbiotic relationship called mutualism, with trees found in the forest. As the
trees carry out photosynthesis, some of the carbon is given to the fungi. Fungi, on the
other hand provide additional nutrients for the trees and help them get more water than
their own root system can accomplish. Fungi are able to extend the root system of the
plant, enabling the plant to gain access to more water and nutrients than would be
possible alone. Another relationship is between trees and moss or algae. Sometimes, moss
or algae grow on the side of a tree, which is benefical because they can receive more
light than would be available on the forest floor amongst the leaf litter. It is an
example of commensalism because the tree is neither harmed nor helped by this
relationship.
