EVERYDAY SCIENCE

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: -r-selected babies grow rapidly, and tend to be found in less competitive, low quality environments. Although not always the case, r-selection is more common among smaller animals with shorter lifespans and, frequently, non-overlapping generations, such as fish or insects.

Detailed explanation-3: -Bacterial Growth Curve representing r and K Reproductive Strategies. K-strategists, on the other hand occupy more stable environments. They are larger in size and have longer life expectancies.

Detailed explanation-4: -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-5: -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.
