What is the difference between biogenous and lithogenous?

The main description of lithogenous came from rocks - Produced as surface rock is broken down by weathering like wind, rain, freezing/thawing. It is transported to the oceans by water, wind and gravity much sediment remains on continental margins. However, some sediment ends up on deep ocean floor as fine rock powder called red clay, brown clay, or brown mud. While Biogenous came from remains of living organisms shell and coral fragments.  Hard skeletal parts of single-cell organisms of either calcareous (soluble shell) material or siliceous (non-soluble, clear, hard) material.
