Question

Human population growth is ____
A. has an S shape curve.
B. is currently in the Logistic phase.
C. is currently Exponential.
D. has reached carrying capacity.

Answer 1

Hint: Population growth is one of the main enterprises of this world because the mortal population is not a stationary factor. Rather, it's growing at a really intimidating rate. In malignancy of the adding world population, the coffers of the world remain constant. Therefore, the power to take care of sustainable development is becoming a serious challenge to humanity at the moment.

Complete step by step solution:
Logistic Growth: This model defines the conception of ‘ survival of the fittest ’. therefore, it considers the very fact that coffers in nature are exhaustible. The limit of coffers beyond which it can not support any number of organisms can be defined as the carrying capacity. The carrying capacity can be represented asK.The vacuity of limited coffers can not show exponential growth. As a result the graph will have a pause phase, followed by an exponential phase, also a declining phase and eventually an asymptote. This is pertained to as Verhulst- Pearl Logistic Growth.
Exponential Growth: In a perfect condition where there is a vast force of food and coffers, the increase will follow an exponential order. Consider a population of size N and birth rate represented as b, death rate as d, Rate of change of N are frequently given by the equation.
dN/dt = (b-d) x N
If, (b–d) = r,
dN/dt = rN
Where r = intrinsic rate of natural increase
This equation is often represented with a graph that features a J shaped curve.
Option C is the correct answer.








Note:
Human increase is the increase in the number of people in a particular area. There has been a drop in the death rate over 200 times due to the changes in public health and sanitation. The arrival of antibiotics and vaccines has led to a drop in the chances of infections in humans. Urbanization and advancements in husbandry have also led to a rise in population.
