Why is the movement of matter among the living(biotic) and non-living(abiotic) parts of this ecosystem important?

Living organisms cannot exist without the nonliving aspects of the environment. For example: air, water, and sunlight, which are all nonliving, are all essential to living organisms. Both nonliving and living things make up an ecosystem. As water being something the living thigs need the water so when it flows through an ecosystem and the living things that water it helps them get it. see what im saying? Also the fish that are in it can help the consmers to eat. Get it?

sediment layers stop spreading when they reach a barrier or they run out of sedimentary material. lateral spreading is the movement of gently to steeply sloping, saturated soil deposits caused by earthquake-induced liquefaction. i hope this . : )
