Behavioral Ecology (Foraging, Parasitism, Mutualism, Mate Choice, and Social Groups)
With a better understanding of ecosystems and their habitats, we are ready to discuss behavioral ecology. This looks at how organisms interact and how this effects the ecosystem. What is foraging? What about parasitism, or mutualism? How...
