Science Assessment ~ Topics ~ Interdependence in Ecosystems ~ Misconception IEM022

If a population in a food web is disturbed, there will be little or no effect on populations that are not within the linear sequence in the food web (Webb & Boltt, 1990).

Items that test for misconception IEM022 in this project (Original Project) and key idea (All organisms, both land-based and …)
Item ID Number	Item Description	How Often the Misconception was Chosen
IE016008	Changes in a population (introduction of a new species) may affect populations that are not directly connected by a feeding relationship (caterpillars) even if they are several steps away in a food web.	37%
IE028006	Changes in a population (frogs) may affect populations that are not directly connected by a feeding relationship (mice) even if they are several steps away and not within the same chain in a food web.	33%
IE028005	Changes in a population may affect populations that are not directly connected by a feeding relationship even if they are several steps away and not within the same chain in a food web (no specific organisms identified).	28%
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.	20%
