Detailed explanation-1: -The production of numerous small offspring followed by exponential population growth is the defining characteristic of r-selected species. They require short gestation periods, mature quickly (and thus require little or no parental care), and possess short life spans.
Detailed explanation-2: -Among the traits that are thought to characterize r-selection are high fecundity, small body size, early maturity onset, short generation time, and the ability to disperse offspring widely. Organisms whose life history is subject to r-selection are often referred to as r-strategists or r-selected.
Detailed explanation-3: -r-selected species are defined as those present in fluctuating environments that have large numbers of offspring and do not provide long-term care after birth.
Detailed explanation-4: -Figure 01: r Strategist r Strategists have shorter life spans and are small in size. They are subjected to predation and have a high mortality rate. The few organisms which belong to this category include salmon, corals, insects and bacteria.
