What functions are performed by the large intestine's
normal flora?

These bacteria are important in digestion and in keeping your large intestine healthy. The good bacteria that live in your colon are called your normal flora. They help prevent bad bacteria from multiplying and causing problems.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
