Question

How does carrying capacity change?

Answer 1

The growth is one of the dynamic features of the species population. Population size increases in a characteristic way. The growth of the population can be measured as an increase in size over a period of time.

Complete answer:
Carrying capacity is defined as the maximum population size that a biological species can sustain in a specific environment with limited resources i.e. food, habitat, water, etc.
The effect of carrying capacity on the dynamics of a population can be modeled using Logistic functions. About carrying capacity the size of the population decreases because of various factors like space Food Supply sunlight etc. that are required by the individuals of a species for their survival. This carrying capacity may vary from one species to another in an environment.
In a population growing exponentially, the initial phase of the growth is slow which then enters a rapid growth phase and finally levels off when the carrying capacity of that population for the species is reached. Above the carrying capacity, the size of the population may fluctuate slightly above or below it. The carrying capacity may temporarily overshoot due to the reproductive lag time of the population. Reproductive lag time is defined as the time required for the both birth rate to decline and the death rate to increase in response to resource limitations.
The carrying capacity of an area is not static and it may be lowered due to resource destruction or degradation during an overshoot. It can also be extended through social or technological changes.

Note: Biotic factors that influence population growth are living organisms or their characteristics. For example, the biotic factors that influence a population are the presence of predators or hunters, the food supply, the density of the population itself and the biotic potential of the diseases and species.
