Predation summary notes
27 June 2023 13:02
Predator- organism that feeds on another organism
know as their prey
- Predators have evolved to become better
adapted for capturing their prey- faster
movement, more effective camouflage, better
means of detecting prey
- Prey have evolved to become better at avoiding
predators- better camouflage, more protective
features such as spines, concealment behaviour
Predation
- Occurs when one organism is consumed by
another
Effect or predator-prey relationship on population size
- Predators eat their prey- reduce population of
prey
- Fewer prey available, predators are in greater
competition with each other for the prey that are
left
- Predator population is reduced as some
individuals are unable to obtain enough prey for
their survival or to reproduce
- With fewer predators left, fewer prey are eaten
and so more survive and are able to reproduce
- Prey population increases
- More prey now available as food- predator
population increases
