1.1.2 quiz: human populations
what does the graph predict about the world in the year 2050?
world population growth
a. earths population will be increasing quickly.
b. the birthrate will be double the death rate.
c. the birthrate and death rate will be nearly equal.
d. the carrying capacity will be decreasing quickly.

Explanation:

• Analyze each option:
• Option A: The slope of the world population line in the graph is relatively gentle in the later years (approaching 2050), indicating that the population is not increasing quickly.
• Option B: The graph does not provide information about birth - rate and death - rate.
• Option C: When the population growth slows down (as indicated by the flattening of the population growth curve for the world), it implies that the birth - rate and death - rate are approaching a balance (nearly equal).
• Option D: The graph is about population growth, not carrying capacity.

Answer:

C. The birthrate and death rate will be nearly equal.
