Question

which of the following match - ups is correct? graph of population growth (population size (# individuals) on y - axis, time (days) on x - axis, with parts a, b, c, d). options: c = exponential growth; d = carrying capacity; a = cyclic growth; b = slow growth

Explanation:

To determine the correct match - up, we analyze each option based on population growth concepts:

1. For the option “C = Exponential growth”: Exponential growth is a J - shaped curve with continuous rapid increase. The part labeled C shows fluctuations around a certain level, not exponential growth, so this is incorrect.
2. For the option “D = Carrying Capacity”: Carrying capacity (K) is the maximum population size an environment can sustain. In the graph, D is a horizontal line that the population (in the C region) fluctuates around, which fits the definition of carrying capacity.
3. For the option “A = Cyclic growth”: Cyclic growth involves regular cycles (like seasonal cycles). The part labeled A shows a slow, initial increase, not cyclic growth, so this is incorrect.
4. For the option “B = Slow growth”: The part labeled B shows a steep, rapid increase, which is not slow growth, so this is incorrect.

Answer:

D = Carrying Capacity
