Does the stingray live in the
photic or aphotic zone?

The photic zone

Explanation:

The photic zone, euphotic zone, epipelagic zone, or sunlit zone is the uppermost layer of a body of water that receives sunlight, allowing phytoplankton to perform photosynthesis. The sunlit zone is home to a wide variety of marine species because plants can grow there and water temperatures are relatively warm. Lots of marine animals can be found in the sunlit zone including sharks, tuna, mackerel, jellyfish, sea turtles, seals and sea lions and stingrays.

Have a great day/night <3 ^^

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.
