O A. evaporation

OB. sublimation

O c. condensation

OD. decomposition

this proce

Decomposition changes the substance of a composition.

Explanation:

Through decomposition process the chemical substance of a composition undergoes change by breaking into organic elements. It falls under the process of cycle of nutrients and it actually recycles matter that captures space in biosphere.
