Chapter 5 test review **What are 3 results of interspecific competition? 1. Competition exclusion = one species completely excludes another species from using the  resource. 2. Neither species fully excludes the other from resources, so both live side by side. a. This produces a stable point of equilibrium, with stable population sizes. b. Species adjust to minimize competition by using only a part of the available  resource. 3. Dividing resources = some specific species eat them at different times than others.  Ex:  Animals hunting at different times of the day. **What are some effects of predation on populations? Increased predator population increases pray.  Predators survive and reproduce. Increased predator populations decrease prey. Decreased prey populations causes starvation of predators. Decreased predator populations increases pray populations. **How does natural selection affect predation? Natural selection leads to evolution of adaptation that make predators better hunters. Individuals who are better at catching prey: Live longer, healthier lives Take better care of their offspring Predation pressure: prey are at risk of immediate death Prey develops elaborate offspring **Describe some examples of predation, parasitism, herbivory, and mutualism.
