6a. Fill in the table below with the expected characteristics of r vs K selected species. r-selected species K-selected species Timing of maturation Longevity Parental care Number of offspring Size of offspring 6b. Based on your table, would a species that provides long-term parental care and has few offspring be considered an r-selected or K-selected species? What is an example of such a species? 6c. Why is long-term parental care associated with having few offspring during a reproductive episode?
