In this example, the phosphate buffer system permits the organisms to maintain a constant pH in their intracellular fluid. This is one of the organism's homeostatic mechanisms.
These are few examples of ecosystem services. These are conditions or processes of natural systems that directly or indirectly have a benefit to humans or enhance their social welfare. They include purification of water and air, maintenance of biodiversity, soil and vegetation generation and renewal, seed dispersal, greenhouse gas mitigation among other services.
