NEET Botany (general) MCQ Question
In an experimental setup, two species of birds were observed for their intrinsic rate of increase 'r'. Species A had an 'r' value of 0.12 per year while species B had an 'r' value of 0.10 per year. If both species are in competition and resources are limited, which species is more likely to persist over time?
Species A, because it has a higher intrinsic rate of increase.
Species B, because it has a lower intrinsic rate of increase.
Both species will persist equally as they have similar 'r' values.
Neither species will persist due to the intense competition.
Correct Answer
Detailed Explanation
Species A with a higher intrinsic rate of increase 'r' is more likely to persist as it can increase its population size more rapidly, outcompeting species B in limited resource conditions.
