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 vary in height and weight according to the region where they  live.    Koalas in northern parts of Australia are smaller, with males  growing to 74 cm and weig â¦ hing 9 kg, and females growing to 72 cm  and weighing 7.25 kg.
