In the autumn, many birds will collect seeds and then hide them in various caches throughout their habitat. the birds will guard their caches from other birds, and move the caches if they start to dry out. these caches provide a food source for the birds during the winter. what is an abiotic factor that contributed to the evolution of this set of behaviors?

The correct answer is temperature and humidity.

The abiotic factors are non-living factors in an ecosystem that affect the organisms and their lifestyle. In this case, low temperature and low humidity lead to the conditions that are unfavorable for birds. So, the birds must adapt to these factors by hiding the food in the caches.

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.
