It states that growth is controlled not by the total amount of resources available, but by the scarcest resource TERM 2
DEFINITION 2 states that the distribution of a species will be limited by its range of tolerance for local environmental factors TERM 3
DEFINITION 3 General process by which animals control solute concentrations and balance water gain and loss. COntrolled by movement of solutes between internal fluids and external environment. Because water follows solutes by osmosis. Birds can do it because nasal salt glands. TERM 4
