Question

In laboratory experiments, two special of the protest paramecium (species 1 and 2) were grown along and in the presence of the other species. The following graphs show growth of species 1 and species 2, both alone and when in mixed culture with the other species.
Which of the following conclusions can be drawn from the graphs?

• A. Competitive exclusive occurred iin these experiments
• B. Both species are affected by interspersion competition but species 1 is affected less
• C. Both species are affected by interspersion competition but species 2 is affected less
• D. Both species are affected equally by intersperse competition

Answer 1

The correct option is C Both species are affected by interspersion competition but species 2 is affected less

When species 1 was kept with species 2, its number of individuals fell drastically while species 2 was kept with species, its number of individuals was not much affected Hence, booth species are affected by inter-specific competition but species 2 is less affected.
