Question

in terms of population growth, which of the following is true:
a a j shaped curve occurs when there are unlimited resources available
b an s shaped curve occurs when there are limited resources available
c in an exponentially growing population, the carrying capacity determines the maximum population that can be supported by the available resources
d a. and b. are true
e all of the above are true.

Explanation:

• Option A: A J - shaped curve (exponential growth) happens when resources are unlimited, as population grows rapidly without constraints.
• Option B: An S - shaped curve (logistic growth) occurs when resources are limited. The population grows until it reaches the carrying capacity, after which growth slows.
• Option C: Carrying capacity is associated with logistic (S - shaped) growth, not exponential (J - shaped) growth. So this statement is false.
• Option D: Since A and B are true, this option is correct.
• Option E: Since C is false, this option is incorrect.

Answer:

D. a. and b. are true
