MCQ
Population termed $r$ - strategists
- ✓Have $J$ - shaped growth curves
- BHave type $III$ survivorship curves
- CAre usually pioneer species
- DAll of these
✓
Answer
Correct option: A.
Have $J$ - shaped growth curves
a
(a) During short period of time, some population produce many offsprings which require little care. Therefore, these populations usually have a survivorship curve similar to type $III$.
(a) During short period of time, some population produce many offsprings which require little care. Therefore, these populations usually have a survivorship curve similar to type $III$.
These tend to have $J$-shaped growth curves until some environmental change causes them to decline usually with in a short time. From an evolutionary point of view, such species have undergone selection to maximize their rate of natural increase and for this reason they are termed as $r$-trategies.
