Two general types of life strategies allow species to thrive in varying types of environment: r-selected strategy and K-selected strategy. Given the following biomes, identify the life strategy that would be more successful in surviving the environmental conditions and provide an explanation supporting your answer.

K-selected strategies involve high levels of parental investment per offspring and lower numbers of offspring per generation, like humans or whales.
r-selected strategies involve less parental investment and more offspring per generation, like mosquitoes or dandelions. (I remember that small-r ["smaller"] organisms tend to have r-selected strategies, but the term really come from its representation of reproduction **rate** in an ecological model called the Verhulst model.)
The two types of strategies perform better in different biomes. Highly stable biomes favor K-selection because the competition gets fierce, so more resources go into preparing offspring with competitive strategies other than fast reproduction.
With small annual variations in temperature or humdity, large populations, tropical rainforests are examples of stable biomes, so they are good contexts for K-selection.
