At the mid-ocean ridges, lava is pushing the sea floor away from the ridge on each side. Eventually that part of the seafloor will be subducted under a continental plate at a convergent boundary. That means that the seafloor is constantly being renewed. The newest rocks will be found closest to the mid-ocean ridge and the oldest the greatest distance from the mid-ocean ridge.
The oldest rock found beneath the ocean dates back only about 200 million years. 
However, the rock underlying the continents is as much as four billion years old.

Schach [20]

Answer:

Zooplankton

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.
