why is it impossibe for an individual organism to simply "adapt" to a new biome?
Adaptation to a new biome takes generations. When in a new biome, many organisms of a peraticular species will die. However, with adaquate variation within the species, some individuals may have characteristics that allow them to survive and pass those (more adaptive) characteristics to their offspring.
With whatever charaacteristics they already have, each individual will either survive or die within a new biome...or within their old biome.
I hope this helps. Thanks for asking.
