Question
If r - selected species find favourable environment they generate ____ number of offspring.
- No
- Few
- Small
- Large
Hint:
The production of numerous small offspring followed by exponential population growth is the defining characteristic of r-selected species. They require short gestation periods, mature quickly (and thus require little or no parental care), and possess short life spans.
The correct answer is: Large
R-selected species often grow quickly and mature rapidly. Combined with their explosive reproductive potential, their quick growth and maturation allow them to colonize disturbed and early successional habitats remarkably well. This is not to suggest that all r-selected species are invasive.
