Question

where has the population reached the carrying capacity in the graph shown above?
a. point a
b. point b
c. point d
d. point c

Explanation:

Step1: Recall Carrying Capacity Definition

Carrying capacity is the maximum population size an environment can sustain, shown as the horizontal asymptote (or plateau) of a logistic growth curve.

Step2: Analyze the Graph Points

• Point A: Population is growing, below carrying capacity.
• Point B: Population is still increasing, not at the plateau.
• Point D: The graph levels off here, indicating the population has reached the carrying capacity (the environment's maximum sustainable size).
• Point C: Typo in option, likely a mistake, but Point D is the plateau.

Answer:

C. Point D
