The carrying capacity of an environment is the maximum population size of a biological species that can be sustained by that specific ... In population biology, ...
In environmental science, a population "overshoots" its local carrying capacity — the capacity of the biome to feed and sustain that population — when that population has not only begun to outstrip its food supply in excess of regeneration, but actually shot past that point, setting up a potentially catastrophic crash of that feeder population once its food populations have been consumed ...
In a population, carrying capacity is known as the maximum population size of the species that the environment can sustain, which is determined by resources available. In many classic population models, r is represented as the intrinsic growth rate, where K is the carrying capacity, and N0 is the initial population size. [5]
Ecological overshoot is the phenomenon which occurs when the demands made on a natural ecosystem exceed its regenerative capacity. Global ecological overshoot occurs when the demands made by humanity exceed what the biosphere of Earth can provide through its capacity for renewal.
where N is the population, r is the maximum growth rate, K is the carrying capacity of the local environment, and d N / d t (the derivative of population size N with respect to time t) is the rate of change in population with time.
The carrying capacity, defined by the variable k, of an environment is the maximum number of individuals or species an environment can sustain and support over a longer period of time. [3] The resources within an environment are limited, and are not endless. [ 3 ]
A common, analogous model fixes the equilibrium, / as K, which is known as the "carrying capacity." Population ecology builds upon these introductory models to further understand demographic processes in real study populations.
Since global hectares is able to convert human consumptions like food and water into a measurement, biocapacity can be applied to determine the carrying capacity of the Earth. Likewise, because an economy is tied to various production factors such as natural resources, biocapacity can also be applied to determine human capital. [12]
