Prey Tell!

Plants and animals are all part of a food chain.  Prey have amazing adaptations to fight or avoid predators, like specialized body parts used as defensive weapons and clever ways of behaving called defensive tactics.

However, no organism has a perfect defence strategy.  If it did, predators would starve!  A healthy ecosystem depends on a balance between the skills of the predator and the defences of its prey.

Prey
Animals that are killed by other animals for food.

Predators
Animals that kill and eat other animals. Does not include parasites, which do not kill their victims.

Ecosystem
Systems that form as, biota, topography, climate, and soils interact, distributing heat, water, minerals, and other chemicals.
