Organic matter builds up evenly over the entire surface of the ocean floor.

Question

Quizplus · Accepted Answer

Organic matter is more concentrated near the surface of the ocean due to the input from phytoplankton and other organisms that perform photosynthesis. As the organic matter sinks to the bottom, it may be broken down by bacteria or become buried in sediment, leading to a decreasing concentration of organic matter with depth. Therefore, organic matter does not build up evenly over the entire surface of the ocean floor.
