Answer:
sunlight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters (656 feet). The ocean is divided into three zones based on depth and light level. The upper 200 meters (656 feet) of the ocean is called the euphotic, or "sunlight," zone.

The biogeographic regions that are the most likely to have species that show convergent evolution are Nearctic and Palearctic.
<h3>What are Nearctic and Palearctic?</h3>
The Nearctic and Palearctic are two of the eight (8) biogeographic regions present on the Earth planet.
Palearctic represents (in turn) the most widely extended biogeographic region present on the Earth planet.
Biogeographic regions are specific areas consisting of particular biological (biotic components) features.
