A team of deep-sea divers and biologists is exploring the open ocean. As team members dive downward from the surface, they observe significant changes to the ocean community at a depth of about 200 meters. What is the main cause of the changes at this depth?

A. loss of brightness of the water
B. increasing salinity of the water
C. increasing temperature of the water
D. decreased oxygen concentration of water

Respuesta :

Answer:

A

Explanation:

sunlight is the main change. sun light cannot penetrate into the deep layers of the ocean and availability of oxygen is also low there. this causes the considerable amount of organisms to live in the upper layers of the ocean and we can only observe decomposing organisms in the deeper layers!
