Detailed explanation-1: -Interspecific competition occurs when members of more than one species compete for the same resource. Woodpeckers and squirrels often compete for nesting rights in the same holes and spaces in trees, while the lions and cheetahs of the African savanna compete for the same antelope and gazelle prey.

Detailed explanation-2: -Interspecific competition can occur between species that are phylogenetically dissimilar, but which use a common resource; an extreme example in inland Australia is competition by feral honeybees with native birds and arboreal and flying mammals for access to hollows in trees (Oldroyd et al., 1997).

Detailed explanation-3: -Some areas the kangaroo inhabits are large farm fields where sheep graze. In these regions kangaroos compete with sheep for grazing land and the dense and nutritious vegetation.

Detailed explanation-4: -Brush wallabies of the genus Notamacropus, like the agile wallaby (Notamacropus agilis) and the red-necked wallaby (Notamacropus rufogriseus), are most closely related to the kangaroos and wallaroos and, aside from their size, look very similar.
