Just to collect one kg of honey, bees must collect nectar from almost 4 million flowers.
                      In the absence of enough food in winter, many animals spend the time in Hibernation, a kind of sleep close to death. Bats, ground Squirrels and and Polar Bears are known to Hibernate.
                       Some ribbon worms (nemertinea) absorb their own body as food till 95 percent of the body is digested, when food is not available. When food is plenty, the lost tissue is restorted!
