biogeochemical cycles
manmade resources...., it is made by man, example is a rice terraces-- you could locate them mostly in Asia (Philippines,etc..) natural ecosystem...., you could see them everywhere, the mountains, hills, etc... it is created by God.... in which you don't have the control on nature...
nitrogen moves through living and non-living ecosystems
Yes they do. For example they cut down trees to build houses etc. They also modify the ecosystem when building roads
The function of cyclin is to regulate the progression of the cell through the cell cycle.
The two processes that sustain ecosystems and the biosphere are one-way energy flow and nutrient cycling. These two processes are linked through the natural services that are components of the earth's natural capital.

is the biogeochemical cycle in which carbon cycles through earth's ecosystems.

we will simply build on top of it and warm it up completely destroying our crops and natural ecosystems ultimately a disastrous end for the human race either through starvation or through the world becoming too warm
Two major ways whereby nitrogen is fixed in ecosystems are through rainfall and through leguminous crops.

biogeochemical cycles
Ecosystems recover from disturbances through ecological succession. This normally happens after a large fire, or the area is wiped out of living organisms.
The answer: the carbon cycle and nitrogen cycle
we do because we through stuff on the ground and pollute the air
