What interactions do they have with
other organisms?
The Red-necked Wallaby is a primary
consumer in the food web. They are herbivores and eat
only plants which are producers. Their two main
predators are dingoes and humans. A dingo is a wild dog
that lives in Australia and parts of Asia.
Humans are
their other predators. They are trapped for their fur,
especially the island subspecies because of their longer
fur. They are exported out of Queensland and Tasmania.
Wallabies are also shot by humans for food, but this as
not as common today as it was in the past. The main
reason however that they are shot is because they are
pests to farmers. They are considered pests because they
compete for food with cattle and sheep. In mobs they can
also be destructive and trample seedlings of farmers
young crops.
The Red-necked Wallaby is an herbivore and it alone can not
break down the cellulose it consumes. They have a mutualistic symbiotic relationship with fungi, bacteria,
and protists that live in their stomachs. A mutualistic
symbiotic relationship is when two organisms live
together and benefit each other. In this case the
bacteria, fungi, and protists live in the stomach of the
wallaby and breaks down the cellulose and other
ingestible materials. They help the wallaby with
digestion, and they benefit by having a food source.
