A pesticide spill occurred near a pond between Year 1 and Year 2. Disturbances can change population dynamics. The algae population (cells per mL) was measured:
  • Year 1 (before spill): 300
  • Year 2: 80
  • Year 3: 120
  • Year 4: 200
  • Year 5: 260
Which explanation best describes the population response using evidence from the data?
