They hunt for other animals.
One of the Arctic Foxes' main sources of food is the Lemming. When there are abundant lemmings the Fox has food to raise large litters and the population of Foxes increases. Similarly the numbers of Foxes that can be fed decreases when the lemming population declines because there is less food for the Foxes. Basically the population of any animal is controlled by its food supply.
Because Kit Foxes do not need to drink anything. Some of Kit Foxes food will not have very much liquid in it to keep them hydrated therefore hey will urinate on their food to get enough liquid into their system.
From the food they eat.
Foxes really are not a food source for humans.
Foxes pee on their food to mark their territory and deter other animals from stealing it. This behavior helps them establish dominance and protect their food source.
Only by eating other food would foxes eat bacteria.
food
yes
They hunt small animals for food.
no
Arctic foxes are generally solitary animals and do not typically share their food with other foxes. However, they may scavenge from the kills of larger predators, such as polar bears, and can sometimes be seen in groups around a large food source. In some cases, family members may share food, especially during the breeding season when parents feed their young. Overall, food sharing is not a common behavior among Arctic foxes.
Because in a simple food web there is no room for adapton and change like there is for a complex food chain. For example, lets say the world was only rabbits and foxes. now the foxes eat all the rabbits and the rabbits become exctinct. So sow with the foxes only source of food gone, they'll starve to death, which in turn, causes the world to turn into an empty wasteland. But with a complex food chain, was as is, the foxes would have mere to prey on which would save the rabbits and the foxes. I hope i helped...
