Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
a plot that shows how the initial exponential growth of a population is slowed and finally brought to a standstill by limiting factors
A
logistic growth curve
B
natural selection
C
ecosystem ecology
D
r-selected species
Explanation: 

Detailed explanation-1: -Logistic growth describes how a population’s initial exponential increase is slowed and finally stopped by limiting factors. Figure 12 shows the S shape of logistic growth.

Detailed explanation-2: -Summary. Exponential growth produces a J-shaped curve.

Detailed explanation-3: -Logistic growth occurs when a population’s growth slows or stops following a period of exponential growth. How might this happen? Logistic Growth This graph shows the S-shaped curve of logistic growth. As resources become less available, the population growth rate slows or stops.

Detailed explanation-4: -When the exponential phase of a logistic growth curve of a population ceases, population growth begins to slow down.
