PPT-Predation

Muzvondiwa JV Outline There are a variety of antipredator adaptations which suggests that predation is important in nature Predatorprey models can explain many outcomes Field data suggests that predators have a large impact on prey populations.

Crowded populations mean the individuals have to compete for food, water, space, sunlight, or anything else necessary for survival and reproduction. 12 June 2013. Overview. Predatory pricing.
