If global warming increases, which animal is most likely to be selected against survival?
The climate changed and the dinosaurs could not adapt
Natural selection is one aspect of evolution
genetic variation
The number of offspring that survive to reproduce
By experiencing mutations over several generations
Polar bear
Upwelling cycles nutrients from decomposers along the ocean floor to producers in surface waters
