Question
Q3. The graphs below represent algae abundance in a limiting-nutrient experiment. Based on the graphs, which nutrients are limiting the growth of algal species A and B in the experiment? (Hint: Recall what a graph of population size vs. nutrient input should look like—straight or sloped—if the nutrient is limiting and also if it is not limiting.)
Algae A is limited by nitrogen and Algae B is not limited by either nutrient.
Algae A is limited by phosphorus and Algae B is limited by nitrogen.
Algae A is limited by phosphorus and Algae B is not limited by either nutrient.
Algae A is not limited by either nutrient and Algae B is limited by nitrogen.

Based on the graph mentioned in the question The algae A is not limited by either nutrient and algae B is limited by nitrogen(d). Also the higher growth in algae A is achieved by phosphorus abundance.
