Which type of organism is likely to thrive in variable environments?

The option indicating that r-selected organisms are likely to thrive in variable environments is rooted in their life history strategies. r-selected organisms are characterized by high reproductive rates, early maturity, and the production of many offspring, but they invest little in each one. This strategy is particularly advantageous in unpredictable or variable environments where conditions can change rapidly.

In such environments, r-selected species can exploit transient opportunities for reproduction. For instance, after a disturbance, like a flood or fire, r-selected organisms can quickly colonize the area, reproduce in large numbers, and take advantage of abundant resources before conditions change again. Their ability to produce numerous offspring rapidly allows them to maintain their populations even when many individuals do not survive, which is common in unstable environments. This reproductive strategy contrasts with K-selected organisms, which are better suited for stable environments where competition for resources is intense and survival rates are higher.
