Answer;
Supply of the most limited resources
Step-by-step explanation;
-The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment.
-Carrying capacity depends on many abiotic and biotic factors in the ecosystem and some are more obvious than others. For example, the availability of the basic needs of organisms such as food, water and shelter dictates how many individuals the ecosystem can sustain. This process is self-regulating to some extent because individuals will die when the carrying capacity is exceeded.
