Question

Quizplus · Accepted Answer

An r-strategist is characterized by density-independent mortality, which refers to factors that affect population growth regardless of the population density. These factors can include natural disasters, climate events, and human activities, among others. Unlike K-strategists, which focus on high survival rates for a smaller number of offspring, r-strategists produce a large number of offspring with little investment in parental care, which results in high mortality rates. Therefore, the slow population growth (A) and slow rate of development (B) are not characteristics of an r-strategist, while the long life expectancy (C) does not apply to most r-strategists.
