Question: I read this background article the other day: An apex predator, also known as an alpha predator or top predator, is a predator at the top of a food chain, with no natural predators.Apex predators are usually defined in terms of trophic dynamics, meaning that they occupy the highest trophic levels. Food chains are often far shorter on land, usually limited to being secondary consumers – for example, wolves prey mostly upon large herbivores (primary consumers), which eat plants (primary producers). The apex predator concept is applied in wildlife management, conservation and ecotourism.  I am facing a new situation today: Two cousins were fascinated about food chains in nature. Liam started reading about apex predators, while Fox read about grazers and large herbivores.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which cousin learned less about wolves?
Answer:
Fox
