dead earth layers fall off the earth like dead skin on us humans. These layers of dead or old organic materials are fertile to our new soil(kind of like fertilizer). Also, like humans a new layer of eath grows in like how a scab falls of and a new set of new skin. This process happens over and over again.
The Earth's biosphere cycles materials over and over by the carbon cycle. The only new matter in the biosphere is the energy from the sun. The total amount of carbon on Earth remains the same, but it takes different forms. Every living thing contains carbon. As living things die and decompose, the carbon is recycled again and again.
