Document Summary
Intraspecific competition: among members of the same species. Competitive exclusion: when one species successfully excludes another from resources. Species coexistence: two species living side by side without affecting each other. Realized niche: fundamental niche: address full nicheall resources; Realized niche: an organism only using some of it"s resources because of competition. Resource partitioning: have birds that become more active in the morning and the other more active at night is a minimizing interference; species divide the resources they use in common by specializing in different ways. Character displacement: competing species come to divergence in their physical characteristics because of the evolution of traits best suited to the range of resources they use. Parasitism: when an organism lives off of another, the host, and does the host harm. Coevolution: long term process of adaptations between a host and a parasite. Herbivory: animals and insects feeding on plants, retarding growth. Natural selection to avoid predation: 1) cryptic coloration (camouflage), 2) warning.
