what is regulation in biology

Organisms and populations can maintain homeostasis in an environment when they have a steady level of births and deaths. Local Regulation is a means of controlling functioning (i.e., homeostasis) in only a very small portion of a bodytypically as involving detection of chemical signalsand modification of immediately local chemistry.
