Explanation:
The modern theory of chemical evolution is based on the assumption that on a primitive earth a mixture of simple chemicals assembled into more complex molecular systems, from which, eventually came the first functioning cell(s).
The answer is descent with modification.
Descent with modification practically means that a species have changed appearance wise over long periods of time to adapt to their environments better.
Plants absorb me from the soil through assimilation, I am eaten by animals the animals and plants die and decompose where I am released back into the soil, weathering and erosion cause me to release out of rocks, I then find my way into the ocean being carried by water, I then return to the soil through the water.
