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.
LIFESPAN: Koalas can live as long as 17 years, although high mortality rates (due to car fatalities and dogs) for males lower their life expectancy to 2 to 10 years. RANGE: The koala's historic range stretches across Australia. Today they can be found only in Queensland, New South Wales, Victoria, and South Australia.HABITAT: Koalas prefer to live in eucalyptus forests, coastal islands, and low woodlands. FOOD: Koalas consume eucalyptus leaves and bark from 12 different eucalyptus tree species.IFESPAN: Koalas can live as long as 17 years, although high mortality rates (due to car fatalities and dogs) for males lower their life expectancy to 2 to 10 years.
