Q7. Another set of nutrient addition experiments is conducted on two additional unknown species of phytoplankton. Results are summarized in the table below. If the two species are grown together under default (baseline) conditions, which of the following will most likely occur and why? Results of Nutrient Addition Experiments, Round Three: Species 4 Nutrient Input Rate Baseline (1x all) 2x N 2x P 2x Si Pop size 100 99 200 100 N P (ug/1) 4000 100 Si (g/l) 5000 4998 Species 5 N P Si (g/L) (ug/L) (ug/1) Pop size 80 3000 29 7999 99 4002 101 4995 152 4001 98 9999 81 2322 4000 4003 29 3998 7998 81 6001 3001 2999 29 Species 4 will outcompete species 5 because it stabilizes at a larger population size than species 5. Species 4 will outcompete species 5 because it has a higher R* than species 5. Species 5 will outcompete species 4 because it has a higher R* than species 4. Species 5 will outcompet species 4 because it has a lower R than species 4
