Lichens, of which more than twenty thousand species have been named, are complex associations between certain algae. The lichen itself is not an organism: rather it is the morphological and biochemical product of the association. Neither a fungus nor an alga alone can produce lichen.
The intimate relationship between these two living components of lichen was once erroneously though to represent mutualism. In mutual relationships, both participants benefit. With lichens, however, it appears the fungus actually parasitizes the algae. This is one of the conclusions drawn from experiments in which the two components of lichens were separated and grown apart.
In nature, lichen fungi may encounter and grow around saveral kinds of algae. Some types of algae the fungi may kill; other types it may reject. Lichen algae are autotrophic, meaning they make their own food through photosynthesis. Lichen fungi are heterotrophic, meaning they depend upon the algae within the lichen to supply their food. Up to ninety percent of than food made by the green alga cell is transferred to the fungus. What, if anything, the fungus contributes to the association is not well understood.
Lichens are hardly. The grow in many habitats and are often pioneers in hostile environments where few other organisms can flourish.
They have been known to grow endolithically, having been discovered thriving inside of rocks in Antartica. Lichen help reduce erosion by stabilizing soil. Saveral kinds of insects glue lichens to their exoskeletons for camouflage.
Many species of birds use lichens as building materials for nests. Human have used lichens for dyes and antibiotics.

Question 6 through 10 based on the following passage
When buying a house, you must be sure to have it checked for termites. A termite is much like an ant in its communal habits, although physically the two insects are distinct.
Like those ants, termite colonies consist of different classes, each with its own particular job. The most perfectly formed termites, both male and female, make up the productive class. They have eyes, hard body walls and fully developed wings. A pair of reproductive termites founds the colony. When new reproductive termites develop, they leave to form another colony. They use their wings only this on time and then break them off.
The worker termites are small, blind and wingless, with soft bodies. They make up the majority of the colony and do all the work. Soldiers are eyeless and wingless but are larger than the workers and have hard heads and strong jaws and legs. They defend the colony and are cared for by the workers.
The male and female of the reproductive class remain inside a closed-in cell when the female lays thousands of eggs. The workers place the eggs in cell and care for them. Even if one colony is treated with poison, if a male and female of the reproductive class escape, they can form a new colony.
Pest control companies can inspect a house for infestation of termites. Often, of lay person can not spot the evidence, so it is critical to have the opinion of a professional. Treatments vary depending upon the type of termite.
