Can anyone tell me what the right order of this nutrient cycle?

the trees of the tropical rainforest receive their nutrients from two sources.

the trees absorb them directly.

dust with minerals (from as far away as the sahara desert) fall with the rain to the
ground.

the ashes from the slash-and-burn agriculture give the soil fertility for about five
years.

in addition, dead plant materials (leaves, branches, etc.) fall to the ground and rot
very quickly to form a thin layer of humus.

they digest the rotting plant material and set the nutrients free.

when the trees are cut down, the cycle is broken.
there is no longer a huge, continuous supply of dead plant material for the
microorganisms in the soil to return the nutrients to the trees.

this takes place very quickly because of the tropical heat and the work of
microorganisms in the soil.
