Answer:
oceanic zone
Step-by-step explanation:
The oceanic zone that contains the greatest biodiversity is the neritic zone. This zone supports coastal communities like coral reefs. Coral reefs are located in warm, shallow, tropical waters. These regions receive ample sunlight to support a booming producer population that can support an abundance of other animals. Coral reefs create many microhabitats that allow for unique niches. These niches support the evolution of many different types of species, which creates the high biodiversity seen in the area.
