Q

what is the effect of predator-prey relationship on population size?

A
  • predators eat prey -> decrease population of prey
  • greater competition within predators for remaining prey

  • decrease in predator population increases prey population as they’re more likely to survive & reproduce
  • increase predator population as more prey available
