Temperature and the amount of precipitation, a combination known as climate, affects the type of plants and animals found in the rainforest biome by directly influencing the ecosystem. The high temperatures and rain create a warm, damp environment that insects enjoy living in, which in turn attracts animals that eat insects, and animals that eat those animals. As a result, many kinds of plants, animals, and insects have all evolved to suit the rainforest environment that nurtures life so passionately. This variety of creatures is known as biodiversity, which is what makes rainforest biomes unique. In conclusion, temperature and precipitation caused biodiversity in rain forests, which affected and still affects plants and animals living in the climate.

Bicarbonate buffer system. Human blood contains large amounts of carbonic acid, which is a weak acid, and bicarbonates, a strong base. If blood pH falls below 6.8 or rises above 7.8, one can become sick or die. This bicarbonate buffer system help maintain blood pH at 7.4. The bicarbonate neutralizes excess acids in the blood while the carbonic acid neutralizes excess bases.
