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
- reduces predator population as some individuals unable to get enough prey for survival/reproduction
- decrease in predator population increases prey population as they’re more likely to survive & reproduce
- increase predator population as more prey available
