The equation for Verhulst- Pearl Logistic Growth is:
Here in this equation “N” denotes Population density (at a point in time ) and “K”dentoes_________?
Natural increase in intrinsic rate
Carrying capacity
Exponential Growth
None of above
Birth rate, mortality rate, immigration, and emigration rates are the key determinants of population increase. There are two primary models for growth:
Exponential expansion is a result of an infinite supply of resources and food. In this situation, the particular organism will grow exponentially.
Logistic expansion – As a result of the scarcity of resources during exponential expansion, individuals compete with one another. This first causes a lag phase. It is followed by acceleration and deceleration. A sigmoid curve shows the growth of a logistic process. Verhulst-Pearl Logistic Growth is another name for this.
Verhulst-Pearl Logistic Growth's equation is:
where N is the population density (at a certain period)
r = intrinsic natural rise rate
Carrying capacity is K.
Option 2 is the correct answer
