Respuesta :
The growth that is exhibited by the foxes at this period is exponential growth. The correct option is B.
What is exponential growth?
The unrestricted growth of a population of organisms that occurs when resources in its habitat are unlimited is known as biological exponential growth.
In the given scenario, the foxes that are moved to new environment, is expanding their population as there is still ample of food available, this is the phase of exponential growth.
Thus, the correct option is B.

The population in the exposed example displays a logistic growth model. There is no independence between population growth and population density because both population density and natality and mortality rates depend on population size.
What happens when the population expands?
When a population expands in a small area, density steadily increases and finally has an impact on the rate of multiplication. As the population grows, the rate of per capita growth declines. The population reaches a maximum point that is determined by the amount of space or food that is available. The carrying capacity, K, refers to this point.
K is a constant that corresponds to the population size at the equilibrium point where the mortality and natality rates are equal.
They can still increase even if N is smaller than K (NK). The population grows less quickly as N gets closer to K. The population reaches equilibrium when N=K, and when N is greater than K (N>K), the population must contract since there are insufficient resources to support its current size.
The logistic growth model is represented by the sigmoid curve. Population growth is first gradual. This happened in the exposed example when the small group of 10 foxes relocated to the new setting and established a new population. The population grows quickly in the second stage. This most likely occurred when fox populations reached 40 individuals. Finally, the population slowly and gradually achieves the equilibrium point, K, which relies on the availability of resources. At this stage, food is becoming more scarce, and most of the available living space is taken.
We could infer that the fox population in the exposed case is approaching its carrying capacity but has not yet reached it because it is still expanding but at a slower rate. The sigmoid curve for this group is about to peak. The population's rate of increase slows when N approaches K.
