Question

Which of the following is Correct for r-selected species?

• A. Large number of progeny with small size
• B. Large number of progeny with large size
• C. Small number of progeny with small size
• D. Small number of progeny with large size

Answer 1

The correct option is A Large number of progeny with small size

r-selected species are those that have high growth rates, exploit less-crowded ecological niches, and produce many offspring, Typical examples of r-species are mice, rabbits, weeds and bacteria, which have a lot of offspring, but a short life expectancy. Features associated with r -selected species include small size and go through irregular and unstable boom-bust cycles in their population size.

So, the correct answer is, 'Large number of progeny with small size'.
