Final answer:
From darkest to brightest, the ocean zones are the bathypelagic zone, mesopelagic zone, and epipelagic zone, with the epipelagic being the brightest as it is at the top layer and receives the most sunlight.
Step-by-step explanation:
The oceanic zones can be categorized based on the amount of light penetration. From the surface down to the deep ocean, the levels of light decrease. The epipelagic zone is the uppermost layer and receives the most sunlight, the mesopelagic zone is below it and experiences a moderate level of light, and the bathypelagic zone is even deeper and receives little to no light, making it one of the darkest parts of the ocean.
Therefore, placing these ocean levels from the darkest to the brightest level of light would result in:
- Bathypelagic zone - Darkest
- Mesopelagic zone - Moderate light
- Epipelagic zone - Brightest
