Answer:
Zooplankton
Explanation:
The correct answer here would be the zooplankton. (see the attached image)
<em>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. </em>
<em>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.</em>
A complex chemistry is most related to maintaining a stable internal environment.
An unidentified prokaryotic cell. Thus, option "4" is correct.
<h3>What atr prokaryotes and eukaryotes?</h3>
Prokaryotes are the unicellular organisms that do not contain nucleus and membrane bound organelle in their cell. Their genetic material is present in the cytoplasm.
On the other hand, eukaryotes have true nucleus that contains the genetic material (DNA). They also contain membrane bound specialised organelles (such as mitochondria, endoplasmic reticulum, golgi complex).
Thus, option "4" is correct.
