Detailed explanation-1: -r-Reproductive strategists are characterized by several life history attributes such as high reproductive rate (higher fecundity), rapid development, short life span, early reproduction, and semelparity.

Detailed explanation-2: -R-selected species are those that produce a large number of offspring and contribute few resources to each individual offspring. They often offer little to no parental care, have high offspring mortality, short life spans, and small body sizes.

Detailed explanation-3: -Organisms whose life history is subject to r-selection are often referred to as r-strategists or r-selected. Organisms that exhibit r-selected traits can range from bacteria and diatoms, to insects and grasses, to various semelparous cephalopods and small mammals, particularly rodents.

Detailed explanation-4: -Examples of r-strategist species are dogs, cats, insects, and fish.
