Q. In laboratory experiments, two species of the protest $Paramecium$ were grown alone and in the presence of the other species. The following graphs show growth of species 1 (left) and species 2 (right), both alone and when in mixed culture

Interpretation of these graphs shows that

A) Competitive exclusion occurred in these experiments
B) Both species are affected by interspecific competition but species 1 is affected less
C) Both species are affected by interspecific competition but species 2 is affected less
D) Both species are affected equally by interspecific competition
Explanation

As we can see from graph 1 that there is more gap between lines of species 1 and 2 than the graph 2. So it is clearly interference out that both species are affected by interspecific competition but species two is less affected
