A mosquito drinking blood (hematophagy) from a human (note the droplet of plasma being expelled as a waste) A rosy boa eating a mouse whole. A red kangaroo eating grass. The robberfly is an insectivore, shown here having grabbed a leaf beetle.
Aquatic feeding mechanisms. Grouper capture their prey by sucking them into their mouths. Aquatic feeding mechanisms face a special difficulty as compared to feeding on land, because the density of water is about the same as that of the prey, so the prey tends to be pushed away when the mouth is closed. This problem was first identified by ...
Cattle feeding. There are different systems of feeding cattle in animal husbandry. For pastured animals, grass is usually the forage that composes the majority of their diet. In turn, this grass-fed approach is known for producing meat with distinct flavor profiles. Cattle reared in feedlots are fed hay supplemented with grain, soy and other ...
Haustellate mouthparts are those used for sucking liquids and can be further classified, by the presence of stylets, which include: piercing-sucking, sponging, and siphoning. The stylets are needle-like projections used to penetrate plant and animal tissue. The stylets and the feeding tube form the modified mandibles, maxilla, and hypopharynx.
Myrmecophagy. The snout and the scientific name of the giant anteater (Myrmecophaga tridactyla) reflect its feeding habits. Myrmecophagy is a feeding behavior defined by the consumption of termites or ants, particularly as pertaining to those animal species whose diets are largely or exclusively composed of said insect types.
Foraging. Grizzly bear (Ursus arctos horribilis) mother and cubs foraging in Denali National Park, Alaska. Foraging is searching for wild food resources. It affects an animal's fitness because it plays an important role in an animal's ability to survive and reproduce. [1] Foraging theory is a branch of behavioral ecology that studies the ...
Nutrition is the biochemical and physiological process by which an organism uses food to support its life. It provides organisms with nutrients, which can be metabolized to create energy and chemical structures. Failure to obtain the required amount of nutrients causes malnutrition.
Definition and related terms. Herbivory is a form of consumption in which an organism principally eats autotrophs [6] such as plants, algae and photosynthesizing bacteria. More generally, organisms that feed on autotrophs in general are known as primary consumers. Herbivory is usually limited to animals that eat plants.
