In the activity on the previous screen, you created a food chain which is the simplest model of energy flow between trophic levels in an ecosystem. This is because these levels represent only one pathway. A food web is another model of energy flow between trophic levels in an ecosystem. Food webs are more realistic than food chains because energy flows between trophic levels in more than one way--and often in very complex ways.
Take a look at this food web and then match the name of the trophic level with the correct number.
