Quantity versus quality: how species balance reproduction and survival
In short: Explore the two extremes of biological growth strategies. This video examines how environmental pressures and resource competition shape the way different organisms approach reproduction and lifespan.
The video contrasts r-selected and K-selected species. K-selected species, such as elephants, tend to be larger and longer-lived, but they produce fewer offspring. In contrast, r-selected species, like frogs, are typically smaller with shorter lifespans, yet they compensate by producing a much larger number of offspring.
