In front of you is an example of a parasitic relationship. The mistletoe plant has attached itself (1)… the oak tree and is using the moisture and food from the tree to feed itself. Sometimes the mistletoe can get (2)… large that it ends up killing its host.
If you are here in the autumn, you will also see that the oak is losing its leaves. Most oak trees are deciduous, meaning they lose their leaves in the fall. You may not remember it, but you even had a deciduous part in your body. Baby teeth are also called deciduous teeth (3)… they fall out as a part of the growing process.
In contrast to the parasitic relationship of the mistletoe and the oak tree, here you see a symbiotic relationship in the lichen (4)… on the rocks at your feet. Lichen are plants made up of a fungus and an alga growing together. The fungi use the food made by the algae, and the algae use the water (5)… by the fungi. The two materials help each other survive. Lichen grow on rocks and trees, and about sixteen thousand species have been identified. Some types of lichen are used as food by animals such as reindeer in the arctic areas and even by humans. Lichens are also used in making perfumes. As you continue your walk, look for the various colors of lichen from gray to green to white. When they are moist, the lichens are usually a bright green.
