If a zebra mussel is discovered in a lake in Pennsylvania, then the ecologist would be worried because it is an invasive species. The zebra mussel is native to Ukraine and Russia, but if it has been found in Pennsylvania, than it means that it has been introduced in this area. As an invasive species, the zebra mussel can be very dangerous for the native species in the lake. The invasive species usually are more competitive for food sources than the native species, manage to reproduce quicker, bring in diseases, and the native species tend to not have defense mechanisms for them. This leads to rapid decline or even extinction in the native species, while the invasive spreads out quickly and takes over, resulting in dramatic change in the whole ecosystem.

B. Mutualistic bacteria in the hindgut of the termite digest the cellulose into sugars
Explanation:
Cellulose is a polysaccharide, cell walls of plant cells are made of cellulose. Termites eat cellulose and live on cellulose for their energy needs. Termites chew dead wood, but for its digestion termites depend on bacteria and protozoa which are present in their gut. They provide enzymes which can digest the cellulose of wood. Thus, they are in mutualistic relationship with termites. These microbes may starve ouside the termite body.
