Plants produce biomass by taking in energy, CO2, and nutrients from the environment; consumers eat much of this biomass, but not all. However, ecosystems do not indefinitely accumulate large quantities of organic matter over time. Why not?
What will be an ideal response?
When consumers eat plant organic matter, much of the carbon is respired, and the nutrients are returned to the soil. Decomposers also recycle much of the remaining organic matter. Many ecosystems do accumulate organic matter, but not indefinitely.
