Final answer:
True, parasites can utilize a wide array of animal hosts. Parasitic adaptability to different hosts is exemplified by species like Trichinella spiralis, and endoparasitism is a common lifestyle for many, including those that cause significant medical and veterinary impacts.
Step-by-step explanation:
True: Parasites can use many animals as hosts, including cows, chicken, pigs, and fish. Many parasites are not that host-specific and can establish themselves in a wide range of species. For example, the parasitic worm Trichinella spiralis can inhabit a variety of mammals and some birds, demonstrating the flexibility some parasites have in terms of host selection. Parasites can cause damage and disease in their hosts and may depend on them for certain life stages. Endoparasitism when parasites live inside their hosts, as seen with roundworms that infest the intestines of cats, dogs, and humans, is a common mode of life. Parasites like filariasis worms are transmitted by mosquitoes and affect many people worldwide.
