NEET Biology question
In laboratory experiments, two species of the protist Paramecium were grown alone and in the presence of the other species. Growth curves for species 1 and species 2 show each growing to a high population when alone, but both show a reduced population size when grown together in mixed culture — species 1's population is reduced more sharply than species 2's. Based on this, what can be concluded?
Answer: (C)
Solution
Since both species reach lower population sizes in mixed culture than when grown alone, both are negatively affected by interspecific competition for the shared resource, but because species 1's reduction is more pronounced than
