Answer:
Correct Answer: A
Solution:
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.
