The Russian scientist G. F. Gause carried out experiments on three species of Paramecium by growing each species separately in identical culture conditions (Experiments 1, 2 and 3) as well as in combination of two species grown together (Experiments 4 and 5). The results of the experiments are shown in the below graphs. Based on the graphs, the correct statement(s) is/are

Options

  1. AThe carrying capacity of the culture media is identical for all the three species.
  2. BP. caudatum and P . aurelia share the same realized niche.
  3. CWhen grown together, P . aurelia utilizes resources more efficiently than P. caudatum.
  4. DCompetition has a negative effect on the growth of P . bursaria and a positive effect on the growth of P . cau

Correct answer

C. When grown together, P . aurelia utilizes resources more efficiently than P. caudatum.
