Question

Why is it useful for scientists to divide the deep zone into three separate zones?

Answer 1

Scientists created each zone of the ocean for the types of organisms living there based on their respective amounts of sunlight, pressure, and temperatures. 75% of the ocean is very deep, dark, and cold.

Step-by-step explanation:

First Zone (depth zero to 200 meters): This is the sunlight zone where photosynthesis is supported along with a wide diversity of fish and other organisms.

Second Zone (depth 200 to 1000 meters): This is called the twilight zone where there is little to no sunlight available and moderately increasing pressure. The temperature within this zone is lower than the first zone and can vary based on weather patterns.

Third Zone (depth over 1000 meters): This is called the deep ocean zone where there is no light whatsoever. The temperature within this zone is extremely cold and the significant pressure limits support for organisms.

Answer 2

Answer: Because every zone of the ocean has the combination of the organisms living there that are adapted to the light, pressure, and temperatures.
