An example is the koala, because it feeds only on eucalyptus leaves. Primary consumers that feed on many kinds of plants are called generalists. Secondary consumers are small/medium-sized carnivores that prey on herbivorous animals. Omnivores, which feed on both plants and animals, can be considered as being both primary and secondary consumers.
Herbivores which consume land plants may eat any or all of the fruit, leaves, sap, nectar, pollen, flowers, bark, cambium, underground storage organs like roots, tubers, and rhizomes, nuts, seeds, shoots, and other parts of plants; they frequently specialize in one or a few of these parts, though many herbivores also have quite diverse diets.

Eucalyptus can produce even more manna than honeydew nectar. The sugar glider eats both, licking the nectar from branches. Other species attracted to the nectar include the feathertail glider, brush-tailed phascogale, and brown antechinus. Most trees are not able to produce sap if the phloem duct becomes damaged by mechanical processes.
It prefers Eucalyptus leaves, but also eats flowers, shoots, fruits, and seeds. [16] It may also consume animal matter such as insects, birds' eggs and chicks, and other small vertebrates. [ 18 ] Brushtail possums may eat three or four different plant species during a foraging trip, unlike some other arboreal marsupials, such as the koala and ...
A well-known example of a specialist animal is the monophagous koala, which subsists almost entirely on eucalyptus leaves. The raccoon is a generalist, because it has a natural range that includes most of North and Central America, and it is omnivorous, eating berries, insects such as butterflies, eggs, and various small animals.
For example, it will not eat plucked eucalyptus leaves on a flat surface, which does not match its feeding routine. [18]: 234 The koala has a broad, dark nose [36] with a good sense of smell, and it is known to sniff the oils of individual branchlets to assess their edibility.

Kleiber's law describes the relationship between an animal's size and its feeding strategy, saying that larger animals need to eat less food per unit weight than smaller animals. [21] Kleiber's law states that the metabolic rate (q 0 ) of an animal is the mass of the animal (M) raised to the 3/4 power: q 0 =M 3/4
