To help him study for a quiz on ecosystems, Ali made a table summarizing the features of the ecosystems he needs to know.EcosystemFeatureIntertidal zonesometimes covered in water, sometimes notNeritic zonesunlight passes completely throughOpen oceandeepest aquatic organisms are found hereCoral reefsrare for life to be found here

The intertidal zone is sometimes covered by water and sometimes exposed, so Ali’s description is correct. The neritic zone receives sunlight, but sunlight does not pass completely through all of it; deeper parts are dark. The open ocean is not where the deepest aquatic organisms are found—that is the benthic zone—while coral reefs are rich in life, not rare for life. So Ali will miss a question on coral reefs, making A correct.
