Question

question 2 of 10
the graph shows the history of human population growth.
growth of human population over history
what kind of growth does the graph show?
a. negative
b. logistic
c. exponential
d. zero

Explanation:

• Negative growth: Would show a downward trend (population decreasing), which is not the case here.
• Logistic growth: Has an S - shaped curve where growth slows as it approaches a carrying capacity. This graph does not show the flattening out characteristic of logistic growth.
• Exponential growth: Characterized by a rapid, accelerating increase (like \(y = a\cdot b^{x}\), \(b> 1\)). The graph of human population growth shown has a very steep upward curve, which is typical of exponential growth (at least in the recent time - frame shown, before any potential limiting factors fully come into play).
• Zero growth: Would be a flat - line (population staying constant), which is not what is depicted.

Answer:

C. Exponential
