Question

microbe population
part a
what is the area of this graph called where the population reaches its maximum level?
a s - curve
b demographics
c carrying capacity
d exponential growth

Explanation:

• S - curve: Represents the logistic growth of a population. It has a lag phase, exponential growth phase, and a plateau phase where the population reaches its maximum level (carrying capacity). But the term for the maximum level itself is not "S - curve".
• Demographics: Deals with the study of human populations (size, structure, distribution etc.). Not relevant to the maximum level of a microbe population.
• Carrying capacity: It is the maximum number of individuals of a species that an environment can support indefinitely. This is the term for the maximum level of the population shown in the graph.
• Exponential growth: Represents a phase in population growth where \(N = N_0e^{rt}\) (\(N\) is population size, \(N_0\) is initial population size, \(r\) is growth rate, \(t\) is time). It is a part of the S - curve but not the maximum level.

Answer:

C. carrying capacity
