What is the difference between r and k strategists

Moreover, K strategists are high in population and therefore, do not have the urge to reproduce rapidly. Thus, they do not show an exponential growth rate. K strategists are larger in size and have longer lifespans.

They have a low mortality rate, and the rate of being harmed is reduced. Organisms such as the humans and the elephants belong to this category. The r strategists live in unstable and unpredictable environments hence they produce many offspring while the K strategists live in more stable and predictable environments hence they make few offsprings. This is the key difference between r strategist and K strategist.

Bacteria, insects and corals are few examples of r strategists while human, primates, and elephants are few examples of K strategists. One other notable difference between r strategist and K strategist is their sizes. The r strategist is smaller in size while the K strategist is larger.

Also, the r strategist shows early maturity and shorter lifespan while the K strategist shows late maturity and longer lifespan. The below infographic presents more details on the difference between r strategist and K strategist in tabular form. The r and K strategists are two types of organisms categories under the basis of r and K selection. On the contrary, K strategist lives in stable, predictable environments. Therefore, r strategist reproduces fast in order to ensure its survival. In contrast, K strategist is much more stable hence does not require rapid reproduction rates.
