I. They produce many offspring in a short period of time II. They have very low survivorship early in life

Explanation:

The r-selected species are the ones who produce the maximum number of offspring as quickly as possible when the resources are abundant. The individuals of the r-selected species have a small body size and exhibit early maturity. They have a short life span and provide little or no parental care to the young ones. Therefore, the survival chances of the young ones in the early stages of life are very low.

These species are found in variable, temporary, or unpredictable environments. Some examples of r strategists are insects, such as mosquitoes, and common weeds, such as the dandelion that produce a large number of offspring as the favorable growth conditions arrive.
