Science Assessment ~ Topics ~ Interdependence in Ecosystems ~ Misconception IEM006

Organisms higher in a food web eat everything that is lower in the food web (Griffiths & Grant 1985).

Items that test for misconception IEM006 in this project (Original Project) and key idea ()
Item ID Number	Item Description	How Often the Misconception was Chosen
IE042006	The size of a population of organisms can increase when its predators are removed from an area because the organisms live longer and have more offspring that also live longer (includes a food web diagram).	15%
IE045003	The size of a population of organisms (deer) can increase when its predators are removed from an area because the organisms can live longer and have more offspring that also live longer (includes a food web diagram).	14%
IE034005	Changes in a population (rabbits) may affect populations that are not directly connected by a feeding relationship (crickets) even if they are several steps away and not within the same chain in a food web.	14%
IE042007	The size of a population of organisms (deer) can increase when its predators are removed from an area because the deer can live longer and have more offspring that also live longer (text only, no food web diagram).	12%
