There are some species who sometimes eat their own kinds. Is this cannibalism considered their regular food? Do the link in food-chain for those animals make a loop on themselves?
Can this statement: "Food chains are found within the population of a species." be held true?
Disclosure: The above statement was part of a question that asked to identify the correct among statements. I tried to find relevant content in books and internet but couldn't find any. I'm not trying to get my assignment solved, but I want opinion on cannibalism and it's impact on food chains.
