Another term for the ocean floor is...
The benthic region
The pelagic region
The neritic region
The oceanic region
Why does the epipelagic zone have the most biodiversity? (different organisms living in it)
Because it has lots of small organisms that don't eat the others
Because the temperature here doesn't change much so fish can adapt easily
Because it is so dark that most organisms can't be seen
Because photosynthesis can happen here so it is full of phytoplankton and food to eat
open ocean; massive area with lots of sunlight and diversity of life
