Summary Introduction
Introduction: The diatoms are the species of the algae found on the sea floor. They are made up of carbon, silica, and other organic matter. The diatoms are degraded after their death due to the degradation by the decomposers present on the seabed. This leads to the changes in the nutrient cycles of carbon and other organic matter on the seabed.
