WebDespite its seeming scientific precision, the claim is old, not new – the latest iteration of the longstanding assertion that our population and consumption might soon exceed the Earth’s fixed ‘carrying capacity’. The concept, tellingly, owes its origin to 19th-century shipping, referring to the payload capacities of steam ships. Carrying capacity is a commonly used concept for biologists when trying to better understand biological populations and the factors which affect them. When addressing biological populations, carrying capacity can be seen as a stable dynamic equilibrium, taking into account extinction and colonization rates. In population biology, logistic growth assumes that population size fluctuates above and below an equilibrium value.
WebThe carrying capacity of an organism is the maximum population size of the species that the environment can sustain indefinitely beyond which there is no further growth. When the population reaches the carrying capacity then mortality becomes greater than natality. Therefore, the correct answer is option B. Solve any question of Organisms and ... WebJul 3, 2024 · 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. It is represented by letter ‘K’. The carrying capacity of any area is not static.
WebWhen the population is at carrying capacity, there is no fluctuation in the birth or death rates. But when there is an increase in the population size above the carrying capacity, there is an overutilization of natural resources such as water, land, etc. Also, there tends to be an increase in pollution-causing many environmental problems.
