Answer 2

Koalas are purely herbivores and only eat certain eucalyptus leaves. They rarely drink water, as all liquid they require comes from the eucalyptus leaves.

Due to the lack of natural predators on the Australian mainland, the koala is near the top of the food chain. Dingoes, an introduced species, eat koalas, and koalas are also subject to predation by dogs that kill for sport, not food.

Koalas are at the top of their food chain. They only eat eucalyptus leaves. Owls have been known to eat baby koalas. Koalas eat up to one pound of eucalyptus leaves per day.

Sun >> Eucalyptus leaves >> Koala >> Dingo or Dog

The Koala (Phascolarctos cinereus) is a marsupial mammal and is indigenous to Australia. Their closest relative is the wombat.

They live in eucalyptus trees and eat only a few types of gum leaves from which they get all nutrients and water requirements. Eucalyptus leaves are tough, toxic and low in nutrition, but the koala has developed a stomach which is capable of removing the toxins from where they are filtered out by the liver. The caecum completes the process by changing the eucalyptus leaves into digestible nutrients. The caecum is similar to the human appendix.

The koala must eat over a kilogram of leaves per day to meet its energy requirements. Eucalyptus leaves contain approximately 50% water, 18% fibre, 13% tannins, 8% fat, 5% carbohydrates, 4% protein and 2% minerals. Koalas have been seen feeding in 120 kinds of eucalypt tree including Manna Gum, Swamp Gum, Blue Gum, Forest Red Gum and Grey Gum.

Answer 4

All species of kangaroo are in the middle of the food chain, but as there are over 60 species of kangaroos, the food chain is different according to the species.

None of the species are at the top of the food chain. Dingoes and eagles are at the top of the food chain, but the larger species most commonly recognised as "kangaroos" (Western Grey, Eastern Grey and Red kangaroo, as well as most wallaroos) are next on the food chain. They are all herbivores.

The smaller species of kangaroos such as wallabies and pademelons have more predators above them, such as hawks and other Birds of Prey, pythons, quolls and, in Tasmania, the Tasmanian devil. These species are also herbivores.

Then there are the tree-kangaroos. They have similar predators, but they are fructivores, or fruit-eaters, not herbivores.

Finally, there are the tiny Musky-rat kangaroos. Their food chain is far more complicated. They have numerous predators larg an themselves, but they are omnivores, feeding on small invertebrates such as earthworms and grasshoppers, as well as vegetation, seeds, fruit and fungi.

Answer 5

The koala is a secondary consumer in the food chain, and a specialist feeder.

Koalas eat eucalyptus leaves almost exclusively, so they are herbivores. Some of the koala's predators are dingoes, dogs, foxes, owls and pythons.

Answer 6

The Koala is a slow moving small herbivore. As long as there is a bigger carnivore present he will never be.

However, due to the lack of natural predators on the Australian mainland, the koala could be regarded as near the top of the food chain. Dingoes, an introduced species, eat koalas, and koalas are subject to predation by dogs that kill for sport, not food. However, they are vulnerable only when they are on the ground, moving between their home trees.

Answer 7

Yes.

The koala is a secondary consumer in the food chain, and a specialist feeder.

Koalas eat eucalyptus leaves almost exclusively, so they are herbivores. In turn, some of the koala's predators are dingoes, dogs, foxes, owls and pythons.

Answer 8

There are several native and non-native carnivores which are in the koala's food chain. Young koalas are vulnerable to owls or pythons. These attacks rare and are insignificant compared to the human related threats and impacts. The main carnivores in the koala's food chain these days are introduced feral animals like the fox and domestic dogs in suburban areas.

Goannas, dingoes, powerful owls, wedge-tailed eagles and other birds of prey, pythons, and foxes all eat koalas, particularly young ones.

The quoll is the only native carnivorous mammal capable of climbing trees to get to koalas. However, a quoll will not take on an adult koala; nor will it challenge a mother koala for a joey carried on her back.

Answer 9

No. Koalas eat eucalyptus leaves, so eucalyptus leaves are lower on the chain.
