Trophic Level Definition Food Chain Food Web Pyramid 46 Off In ecology, the food chain is a hierarchical classification of different predators and prey that usually reflects the ecological trophic levels The food web, on the other hand, is a networked In a food web, organisms are arranged according to their trophic level An organism's trophic level refers to how it fits within the food web and is based on how it feeds There are two main

Trophic Level Definition Food Chain Food Web Pyramid 46 Off Where do humans fall in the food chain? You can probably already guess it’s somewhere between cows and polar bears, but a new study now puts a number to it: Somewhere between 20 and 26 In the new study, ecologists specifically calculated human's trophic level — a number between 1 and about 55 that tells you how much energy it takes to make a species' food Plants and algae It's a platitude that we've all heard dozens of times, whether to justify our treatment of other species or simply to celebrate a carnivorous lifestyle: humans are the top of the food chain In 2009, the median global human trophic level was a paltry 221 To estimate human trophic level, researchers used food supply data for 176 countries from 1961 to 2009 provided by the Food and
