Question

Food webs such as the one shown were first used in 1927 by the animal ecologist charles elton. the food web below represents the feeding relationships among organisms in an alaskan ecosystem. an environmental change that removed which of these organisms from the ecosystem would cause the most instability in the ecosystem?

Answer 1

Zooplankton

Step-by-step explanation:

The correct answer here would be the zooplankton. (see the attached image)

Due to the important position of the Zooplankton in the food web, any change in the environment that removes them will cause the most instability in the ecosystem.

Five different organisms within the food web directly depend on the zooplankton for their food four of which have no any other option. Removal of zooplanktons from the environment will directly affect these organisms and this will throw the entire food web into disarray.
