Question

population size (per leaf)
time elapsed (days)
based on the graph, what is the plants approximate carrying capacity per leaf for aphids?
22
225
410
440

Explanation:

Step1: Understand Carrying Capacity

Carrying capacity is the stable population size a habitat can support. On the graph, after some time, the population stabilizes (flattens out).

Step2: Analyze the Graph

Look at the later part of the graph (around day 16 - 22). The population size per leaf stabilizes around 410 (the points are around 410, not 22, 225, or 440; 440 is above the stable points, 22 is time, 225 is too low).

Answer:

410 (from the option "410")
