For each algal species they have to figure out which nutrient is limiting, and what happens when that nutrients is increased. Then, based on the individual growth trajectories, students try to predict which will win out when they are grown in pairs or all together. They also try to predict the winners when a density-independent death rate is incorporated into the model.\r\n\x3c/span\x3e\x3cbr/\x3e\n\x3cbr/\x3e\n\x3cstrong\x3eLevel\x3c/strong\x3e: Intro\x3cbr/\x3e\n\x3cstrong\x3eKey Concepts\x3c/strong\x3e: Competition; Limiting nutrients; Nutrient ratios\x3cbr/\x3e\n\x3cstrong\x3eCourses\x3c/strong\x3e: Aquatic Ecology; Ecology; Ecosystems; Environmental Science\x3cbr/\x3e\n          \x3cbr/\x3e\x3ca href=\"/search_result_details/brief/58\" class=\"node_brief\"\x3eRead less\x3c/a\x3e        \x3cbr/\x3e\x3ca href=\"/cart/add/58\"\x3e + Add to course collection\x3c/a\x3e  \x3c/span\x3e \x3c!-- description --\x3e\n" }
