Detailed explanation-1: -The three common types of tapeworms are Taenia solium, found in pork; Taenia saginata, found in beef; and Diphyllobothrium latum, found in fish. Tapeworm eggs are for the most part ingested through food, water, or soil contaminated with human or animal host excrement.

Detailed explanation-2: -The symbiotic relationship between a tapeworm and a pig is parasitism. Parasitism is when one species benefits (parasite) while harming/hurting the other species (host).

Detailed explanation-3: -Parasitism occurs when two organisms interact, but while one benefits, the other experiences harm. Parasites harm their hosts, as with the tapeworm attaching itself to the intestine of a cow; the tapeworm absorbs the nutrients from the cow’s diet, preventing them from being absorbed by the cow.

Detailed explanation-4: -Pigs become infected by eating tapeworm eggs in the feces of a human infected with a tapeworm. Both the tapeworm infection, also known as taeniasis, and cysticercosis occur globally.
