There are many specialized structures that animals use in feeding. Some animals use sharp teeth while others use sheer arm power.
Some animals with a radula include snails, slugs, and certain types of mollusks like chitons and some species of squid and octopus. These animals use their radula, which is a specialized feeding structure with tiny teeth, to scrape and shred food.
Periwinkles are small marine snails that primarily feed on algae, diatoms, and other plant material. They use their radula, a specialized feeding organ, to scrape algae from surfaces and consume it as their main source of food.
"Vivisection is a cruel way of testing drugs on animals."
This is a vague usage of words, for all animals that have a nose have a proboscis, technically speaking. But if you mean animals that use a long protruding mouth part that sucks or pierces and sucks, it could be various insects like mosquitoes, butterflies, and assassin bugs. And even elephants can somewhat fall into this category.
There are quite a few animals with the ability to suck food through tubes. Humans for example can do this.
Some animals that use filter feeding to obtain food include baleen whales, manta rays, and sponges. These animals passively capture food particles from the water by filtering them out with specialized structures or mechanisms.

what types of structures help animals get energy
Insects acquire their food through various methods such as feeding on plants, other insects, decaying matter, or by sucking blood from animals. They use their specialized mouthparts to consume and digest their food.
Many animals use adaptive structures to get food like the animal may wait until the other animal is dead like a vulture.
Animal-like protists in the phylum Sarcodina are known as amoebas. They move and feed by extending and retracting pseudopods, which are temporary bulges of the cell membrane. Amoebas primarily engulf food particles through phagocytosis.
Animals use various mechanisms such as lungs for gas exchange, gills for aquatic respiration, digestive systems for nutrient absorption, and skin for diffusion of gases and wastes. Additionally, animals have specialized structures like alveoli in lungs, villi in intestines, and capillary networks to increase surface area for efficient exchange of materials. Some animals also use specialized respiratory pigments like hemoglobin to enhance the transport of oxygen.
Some animals with a radula include snails, slugs, and certain types of mollusks like chitons and some species of squid and octopus. These animals use their radula, which is a specialized feeding structure with tiny teeth, to scrape and shred food.
they would use if ror firewood and for feeding there animals with food from the woods
short, hairlike strands called cilia sourround a paramecium. They use them for feeding and movement.:)
Rice is used for feeding animals, and us. We also use for making paper.
