1 Lesson aims We are going to learn about the effect of competition on populations and strategies shown by organisms to reduce it. Graph (a) shows the population size of two protoctistan organisms when cultured separately. Graph (b) shows the effect of culturing them together. What conclusion can you make about the organisms?
