Question
r- selected species expand ____.
- Normally
- does not expand much
- Rapidly
- Slowly
Hint:
r- selected species expand rapidly
The correct answer is: Rapidly
r-selected species are those that emphasize high growth rates, typically exploit less-crowded ecological niches, and produce many offspring, each of which has a relatively low probability of surviving to adulthood (i.e., high r, low K). A typical r species is a dandelion (genus Taraxacum).
