The way a season affects an animal all depends on the species and/or environment. For example: animals usually found in the woods or forests (bears, foxes, rabbit, etc.) hibernate during the winter because of the lack of food during winter. I don't know all the affects, but that was an example of how winter affects woodland animals.
No. Platypuses feed on the same food throughout the year, as their food source does not tend to change with the seasons.
Several different kinds of animals change their coats with the seasons. Ferrets, stoats, and rabbits are just a few examples of animals that change their coats with the seasons.
No, it's just how it was formed. But if you untilted it now a lot of Earth's properties would change. For example, there would be no change in daylength throughout the year. This might affect things like the migration of birds. You would also have no seasons. At each latitude, the climate would be consistent throughout the year. That would probably upset a few things, since the annual cycle of most plant species, and the reproductive cycle of most birds and small animals, is tied to the seasons. Almost as if they evolved to their present forms in response to the presence of seasons.
Maybe that start to dramatically change temperatures
How animals know how to change with the seasons is because all animals have sensors and those sensors don't go " hey come on its time to go north" it just gives them the info like it would vibrate.
it is camouflage
Seasonal dimorphism.
To camouflage them for the change in their environment
No, the climate stays the same but the weather changes with the seasons.
Yes. Seasons can change the size of populations
Yes, the tilt of the Earth's axis is responsible for the change in seasons. This tilt causes the different hemispheres to receive varying amounts of sunlight throughout the year, leading to the four seasons.
well there would be no seasons
