Document Summary
Competition, coexistence, competition-colonization tradeoff, resource allocation, adaptation, herbivore resistance. Competition two or more species require the same resources (food, water, shelter, space, etc. ) to survive they compete for them and the superior competitor can drive the other species extinct or exclude it from an area. Interaction of species living among each other, can do this through: competition, resource partitioning, increased defenses against predators, and positive interactions with other species. Reduces competition among the species and allows them to coexist. Roots of each species take up water and mineral ions from a different soil depth. Herbivore resistance (textbook definition) a change within an organism or species which allows it to become better suited to its environment. Plants can develop physical or chemical defenses against herbivores. Feedback mechanisms, positive and negative, examples of each. A process whereby a change to the system will trigger a certain result.
