constriction. web. predation, in animal behaviour, the pursuit, capture, and killing of animals for food. Predatory animals may be solitary hunters, like the leopard, or they may be group hunters, like wolves. The senses of predators are adapted in a variety of ways to facilitate hunting behaviour. Visual acuity is great in raptors such as the ...

Oct 2, 2023 · Herbivores are defined as animals that primarily consume and survive on plant matter, including leaves, stems, roots, bark, grasses, nuts, seeds, fruit, algae, etc. Herbivorous diets represent a specialized feeding strategy that relies on adaptations to find, handle, digest, and extract nutrients from fibrous, cellulose-rich plant materials ...

A herbivore is an animal, aquatic or terrestrial, that is adapted to eat plants and no meat. Although such animals are sometimes referred to as being vegetarian, this term is more properly reserved for humanswho choose not to eat meat as opposed to animals that are unable to make such choices. Herbivores differ in the extent, specificity, and natur...
Our understanding of herbivory in geological time comes from three sources: fossilizedplants, which may preserve evidence of defense (such as spines) or herbivory-related damage; the observation of plant debris in fossilized animal feces; and the construction of herbivore mouthparts (Labandeira 1998). Long thought to be a Mesozoic phenomenon, evide...
Plant defenses
Plants have an enormous array of mechanical and chemical defenses against herbivores, allowing them to improve their chances of survival and reproduction. These defenses include mechanical protections on the surface of the plant, production of complex polymers that reduce plant digestibility to animals, and the production of toxins that kill or repel herbivores. Defenses can either be constitutive, always present in the plant, or induced, produced or translocated by the plant following damage...
Herbivore adaptations
Herbivores are dependent on plants for food and themselves have diverse mechanisms to obtain this food despite the varied arsenal of plant defenses against herbivory. The adaptations of herbivores that allow them to overcome plant defense have been likened to “offensive traits” and consist of those traits that allow for increased feeding and use of a host (Karban and Agrawal 2002). For example, bovids have mutually beneficial symbiotic relationships (mutualism) with bacteria and other microor...

Attribution. When an animal feed on parts of another organism (usually a plant), herbivory occurs. For example, the koala eats the eucalyptus leaves (figure 6.1.1.2.a 6.1.1.2. a) or a cicada feeds a plant's sap (figure 6.1.1.2.b 6.1.1.2. b ). Like predators, herbivores may feed on multiple individuals over their lives; however, herbivores do ...

Deer: some examples of these herbivorous mammals are elk, reindeer, red deer, and caribou, also being polygastric. Learn more with our article on the different types of deer. Equidae: they are monogastric and include donkeys, horses and zebras.

Figure 34.2.1 34.2. 1: Examples of herbivores: Herbivores, such as this (a) mule deer and (b) monarch caterpillar, eat primarily plant material. Some herbivores contain symbiotic bacteria within their intestines to aid with the digestion of the cellulose found in plant cell walls. Omnivores are animals that eat both plant- and animal- derived food.
