Misconceptions of Trophic Levels
and Energy Transfer
Food webs are linear
Truth: A food web is a system of interlocking & interdependent food chains that depict the flow of energy within an ecosystem
Food chains & Food webs are the same thing
Truth: A food web consists of many food chains; In a food web, a particular organism has the probability of being eaten more than just one organism
Carnivores have more energy or power than herbivores do
Truth: While some carnivores may require more food than herbivores, they do not have more energy or power
There are more herbivores than carnivores
Truth: There are more herbivores than carnivores because of the decreasing amount of energy available at each level of the food web
Decomposers are an insignificant part of the food web
Truth: Decomposers break down dead organisms, returning nutrients to the soil so they can be used by plants
Species coexist in ecosystems because of their compatible needs and behaviors
Truth: Species compete for resources and feed on one another
Organisms higher in a food web eat everything that is lower in the food web
Truth: Organisms higher in a food chain eat some, but not necessarily all, of the organisms below them in the food web
Arrows in the food web represent who eats who
Truth: Arrows in the food web represent the flow (gain or loss) of energy
