Answer

Answer is c) logistic

Answer

When resources are limited, populations exhibit logistic growth. In logistic growth, population expansion decreases as resources become scarce.

Answer

Logistic Growth Curve Explanation:

Population growth can be represented by different types of growth curves depending on the pattern of growth. One common type of growth curve is the sigmoid or logistic growth curve.

Key Points:
- The sigmoid growth curve is characterized by an initial phase of slow growth, followed by a rapid increase in growth, and then a plateau phase where growth levels off.
- This type of growth curve is often seen in populations where limited resources, such as food or space, constrain further growth.
- The logistic growth curve is a type of sigmoid curve that models population growth when resources are limited.
- In the logistic growth curve, the population initially grows slowly as it approaches the carrying capacity of the environment.
- Once the carrying capacity is reached, the growth rate slows down and eventually stabilizes at the carrying capacity level.

Explanation:
- The sigmoid growth curve is different from exponential growth, which shows unlimited growth without any constraints.
- In the sigmoid growth curve, the population reaches a point where resources become scarce, leading to a decrease in the growth rate.
- This type of growth curve is more reflective of real-world population dynamics, where environmental factors play a role in regulating population growth.

In conclusion, the population growth curve is sigmoid if the growth pattern is logistic, reflecting the natural constraints on population growth imposed by limited resources.
