A fundamental constant is one that has to be measured by experiment, rather than being derived from any other quantities. Which values we choose to make fundamental and which ones are derived are somewhat arbitrary.
Koalas are native to southeastern and eastern Australia, living in forests of eucalyptus trees. They are basically sedentary animals that need to sleep a lot to give them time to digest their food. Being on the ground all the time would be a disadvantage, because predators could catch them easily.
Koalas do not live all over Australia. The koala lives mostly within the temperate zones of Australia. Its habitat is eucalypt woodland and bushland, but of the several hundred species of eucalyptus (gum trees), koalas prefer about 60 varieties, with their specific preferences being limited to a couple of dozen.he koala lives mostly within the temperate zones of Australia.
