Scientists have long wondered how Australia's koalas get enough water to live.A new study p（1）rovidesrovides an answer.
The lead writer of the new report on koalas is Valentina Mella of the University of Sydney.It was the earlier i（2）deadea，she explains，that the animals got most of the water they needed in the leaves they ate.
In the wild，koalas get water from the plant leaves they eat.But they also get it from water r（3）unningunning down from the trees when it rains.Mella and other scientists w（4）atchatch koalas in the wild every year.They find that koalas are a（5）ctivective at night.They live in trees and depend on them for food，drinking and also for resting places.
Koalas spend most of the time high up in the trees.They eat lots of leaves.An adult koala normally eats b（6）etweenetween 0.5 and 0.8 kg of leaves a day.Koalas sleep about 20 hours a day.
Mella notes that a koala usually spends 98% of its 1（7）ifeife in trees.She also notes that the only time they come down to the ground is to discover another tree with b（8）etteretter leaves.
In fact，the word "koala" means "no drink" in the l（9）ocaoca language.Koalas did not go down onto the ground very often.So it was considered that they had no n（10）eedeed to drink water.
The koalas' living environment is getting worse now because the recent fires in Australia have burned about 30% of the forests where they live.
