Question

The point at "A" on the growth curve is best described by: A. exponential increase in population size, or r_max B. population size is at carrying capacity C. population size where K-N/K is approaching 0 The point at "B" on the growth curve is best described by: A. exponential increase in population size, or rmax B. population size at carrying capacity C. population size where K-N/K is approaching 0 The point at "C" on the growth curve is best described by: A. exponential increase in population size, or r_max B. population size at carrying capacity C. population size where K-N/K is approaching 0

Explanation / Answer

Answer 9:- Option A

Explanation:- Point A of the growth curve is best described as exponential increase in population, as the point represents the exponential growth phase. Also, the point A represents the J shaped growth curve, which symbolizes exponential growth.

Answer 10:- Option B

Explanation:- Point B denotes the stationary phase of the growth curve. Stationary phase occurs when the number of individuals gets large enough, resources start to get used up. It slows the growth rate. Eventually, the growth rate reaches a plateau, or level offs. The population size, at which it levels off, represents the maximum population size a particular environment can support and is called as the carrying capacity. As point B denotes this plateau region in the growth curve, it shows population size at carrying capacity.

Answer 11:- Option C

Explanation:- Logistic growth produces an S-shaped curve as shown in the question. Logistic growth takes place when growth rate decreases as population size approaches a maximum imposed by limited resources, the carrying capacity. Thus, when K-N/K approaches 0, the curve bends to form S-Shape. Point C denotes the population size where K-N/K is approaching 0.
