The more species disappear, the more entire eco-systems become vulnerable and would eventually fall apart as the links in the food chains become broken.

 why is ph important in biological systems

why is ph important in biological systems

in order to maintain a relatively stable pH. Note that the function of a buffer is NOT to keep a solution neutral (at pH 7); its function is to minimize the change in pH when base or acid is added to the solution. Also note that there are many different buffers, and each one will stabilize the pH of a solution only within a specific pH range. One buffer may be effective within a range of pH 2 to pH 6, while another may be effective within a range of pH 10 to pH 12. Beyond its buffering range, a buffer no longer acts to stabilize the pH of the solution. Buffers are extremely important to living organisms because most biochemical processes proceed normally only when the pH remains within a fairly narrow range. An excess of H can interfere with the structure and activity of many
