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.
The koala (Phascolarctos cinereus) is herbivorous marsupial animal that is endemic to Australia. These animals are known to reside in the eastern as well as southern Australia that ranges from Adelaide and extending to the Cape York Peninsula.
