Eugene Odum 1912 - 2002 Dr. Odum brought prestige to the little- known field of ecology, helping to transform it from a subdivision of biology into a widely taught discipline of its own. Predator prey.ppt - Google Slides Predator Prey Relationships Learning Objectives Be able to describe the relationship between predators and their prey. When prey organisms develop an effective defense against predation, predators must adapt to the change and find a way around the defense, or find a new organism to prey on. Predator Adaptations - General Predators have adaptations to catch and consume their prey. Although the consumption of prey directly by . The predators learn faster, and fewer butterflies of both species are eaten during the learning process.
