Study Notes
Predation
- Interaction between species where one organism (predator) consumes another organism (prey).
- Crucial for maintaining ecological balance and ensuring biodiversity.
Predator
- Organism that hunts and kills other organisms for food.
- Adapted with traits for hunting, such as sharp teeth, claws, or camouflage.
Prey
- Organism that is hunted and consumed by a predator.
- May develop defenses such as speed, camouflage, or toxins to avoid predation.
Predation and Population Growth
- Predators regulate prey populations, preventing overgrazing and promoting diversity.
- Fluctuations in predator and prey populations often follow a cyclical pattern.
Parasitoidism
- A specialized form of predation where a parasite ultimately kills its host, unlike a true parasite which does not.
- Parasitoids typically lay eggs inside or on their hosts, which are consumed by the developing parasitoid larvae.
