A:

Quick Answer

According to a research report that was published in “Proceedings of the National Academy of Sciences,” pigs rank in the middle of the food chain with a trophic level between 2 and 2.5 on a 5 point scale, according to Popular Science. This is the same trophic level given to humans as a whole.

The trophic level of any species is determined by its diet of plants and meat. The more meat a species eats, the higher its trophic level. Plants generally have a trophic level of 1, whereas a killer whale has a trophic level of 5. Just like humans, pigs eat a balanced diet of both meat and plants, so they fall in the middle.

Not all pigs have the same trophic level. The trophic level of pigs varies depending on what country they live in, because this plays a huge role in the animal's diet. Humans are another good example of this. For example, researchers say that the trophic level of people living in Iceland, Mongolia and Mauritania is higher than that of people in other areas of the world. This is because people in these areas of the world have diets that are based primarily on fish, dairy and meat. The trophic level also tends to be lower in more developed countries, where people put more fruits and vegetables on their dinner tables.
