Q1.5. Based on the data in the table below, which of the following most likely correctly identifies the limiting and secondarily limiting nutrients for species 3? Results of Nutrient Addition Experiments, Round Two: Species 1 Species 2 Species 3 Nutrient Input Pop Rate Si Pop Si Pop Si Baseline (1x all) 100 240 100 5000 80 3000 50 4000 50 4000 55 120 200 242 101 4998 79 6005 49 4003 50 4002 54 122 100 240 201 4995 158 2999 48 3998 50 3998 110 100 100 239 99 9999 81 3002 49 7998 94 3995 22 150 2x P 2x Si N is the primary limiting nutrient, P is secondarily limiting P is the primary limiting nutrient, Si is secondarily limiting Si is the primary limiting nutrient, P is secondarily limiting Si is the limiting nutrient, N is secondarily limitingExplanation / Answer
2nd option is right, P ( phosphorus) is the primary limiting nutrient because it follows the Libig's law of minimum that is its minimum quantity is needed for optimal growth of the plant/ crop. There is 3 primary nutrient declair for the limiting factor , N, P K and between these only N and P are present in all 3 species . P is needed in minimum quantity and increase in amount leads to the maximum growth of species.
On the other hand, Si (silica) is considered as secondary limiting nutrient because it is other macronutrient which support growth but not limits the growth but needed for to achieve the maximum growth .from the above table you can see that increase in huge amount of Si doest not relatively enhance the population size so this is not primary limiting factor.
