Answer: you have twilight zone and sunlight zone but all I could find was sunlit zone
This is all I know about sunlit stuff problem no help tho
Step-by-step explanation:
One adaptation is small size. The most numerous organisms of the sunlit zone, the zooplankton, are small. When you are small, not only are you hard to see, but it is easier it is to stay afloat. If an organism is small and light it can stay up in the water column longer.
