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 live in southeastern and eastern Australia â in the states of Queensland, new South Wales, South Australia and Victoria â in the eucalyptus forests and woodlands. They live in eucalyptus trees and spend most of their time wedged between forks in the tree's branches.
