The expression “K– N” is equal to the number of individuals that may be added to a population at a given time, and “K– N” divided by “K” is the fraction of the carrying capacity available for further growth. The term carrying capacity typically refers to the capacity of a vehicle or container, or, in ecology, the capacity of a region to support life.. We often, however, dont make the connection that the amount of available resources dictates the size of a population that a population will grow when resources are in surplus, decline when resources are scarce, and stabilize when the population is at the maximum level that can be sustained.

In the first century AD, the global population was estimated to have been 300 million people, which then took 1,800 years to reach a population of 1 billion in the 19th century. According to research and historical census evidence, the global population has grown over 100% faster in the last 100 years than in the last 1,500 years. Human population, now over 7 billion, cannot continue to grow indefinitely. largest number of individuals of a population that a given environment can support. Factors that limit wildlife populations include: To be concrete, consider a low density growth rate r = 0.4 and a carrying capacity M = 1000.
