Answer:
O It allows for an increase of oxygen in sediments.
Step-by-step explanation:
The presence of sediments and water in a habitat generates that the water molecules oxygenate these sediments, and that also generates a micrometric system where the drainage of the same fluids works better.
These sediments generally accumulate, generating sedimentation rocks over time, or accumulating precipitously at the bottom of pools of water.
Once the rocks or firm sediments are formed there, some microorganisms such as bacteria or the fungi kingdom may accumulate.
