Refer to the figure.
The figure shows data from a study on goldfinches that determined how foraging behavior changed with group size (referred to as "flock size").
- Suppose that each individual bird can eat 2 seeds every 5 seconds and that there are a maximum of 100 seeds in any one patch. For a flock of 16 individuals, how long would it take the flock to eat all of the seeds in the patch?
A) Less than 5 seconds
B) 5-10 seconds
C) About 15 seconds
D) About 20 seconds

Quizplus · Accepted Answer

Each bird eats 2 seeds in 5 seconds, so 16 birds eat 32 seeds in 5 seconds. To eat 100 seeds, it would take them about 15 seconds (since 32 seeds per 5 seconds means 96 seeds in 15 seconds, which is close to 100).
