NEET Biology question

In laboratory experiments, two Paramecium species (species 1 and species 2) were grown alone and in the presence of the other species. Growth curves show reduced population size for both species when grown together in mixed culture, with species 1 showing a smaller reduction and species 2 a larger reduction compared to when grown alone. Which conclusion can be drawn?

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