3. Trichonympha and other microbes supply cellulase, the enzyme needed to break down cellulose, which is the primary chemical constituent of wood and other fibrous plant parts. What ecological consequences would ensue if we did not have trichonympha and other organisms producing this enzyme?
4. how could antibiotics designed to stop narrowly defined categories of infectious microbes be used to discover which organisms are mutualists and which are parasites or commensals in the termite gut?
5.Human beings carry a diverse community of bacterial species in their large intestine, including Escherichia coli strains that rarely cause disease in healthy people. The normal bacterial flora outcompetesany foreign bacterial species passing through the system. Based on these facts, is it understandable that antibiotics taken for a sore throat might cause intestinal discomfort?
