(described): Population Cycles of Two Pond Species A line graph plots population (individuals, y-axis from 0 to 600) against time (weeks, x-axis from 0 to 12). Curve M (a prey species) rises to a single peak of 500 individuals at week 4, then declines to a low of 120 at week 10. Curve N (a predator species) rises to a single peak of 250 individuals at week 8, then declines to a low of 60 at week 12.
Based on, by how many weeks does the predator's population peak lag behind the prey's population peak?
- 2 weeks
- 4 weeks
- 6 weeks
- 8 weeks
