Answer:
Chemical weathering
Explanation:
Chemical weathering is the process when rain chemicals react with rocks and minerals. In this process, the rocks are weakened. This chemical happening provokes the chemical reaction in the rock or in the mineral.
Chemical weathering is a spontaneous process and it leads to a more stable state for natural materials under a given set of conditions.

Protozoa have been classified into three trophic categories: the photoautotrophs which harness the sun's radiant energy in the process of photosynthesis; the photoheterotrophs, which although phototrophic in energy requirements, are unable to use carbon dioxide for cell synthesis and must have organic carbon compounds
The given blank can be filled with enzymatic molecules.
Enzymes refer to biological molecules or proteins, which function as catalysts and assist the composite reactions to take place everywhere in life. The enzymes generally end with the suffix - ase. For example, proteases, which functions to dissociate the peptide bonds between the amino acids.
Enzymes are big molecules, which accelerate the rate of chemical reactions within the cells, and like all other kinds of proteins, they comprise lengthy chains of amino acids.
