Document Summary
Plants: a, a, pre-emptive competition, primarily among sessile organisms (non-mobile) in a physical resource (space) Sponges, coral, oysters: ex: joseph connell- gb examine 2 species barnacles. Barnacles are attached to rocks, piers, docks, boat hull, whales. Larval are free swimming, they float in the ocean current (tiny: land on a rock, dock, whale become fixed and grow, they spend their entire life in that spot, chthamalus stellatus (cs) smaller barnacle. At low tide: sb are underwater and cs are exposed why. Intertidal zone: the distribution of competition of cs & bs. Results: cs survived but sb died because sb is sensitive to drying. Paramecium are single celled organisms: herbivores = eat plants, carnivores= eat meat, omnivores= eat everything. Pa & pc eat the same food resource: two flasks graph 2. Experiment 2: pa + pc: graph 3 pa fast swimmer ate all the food before pc because they swim slower than pa, pa outcompeted pc the limited food resource ix.
