How does the release of carbon dioxide by microorganisms benefit plant life? a. it reduces the acidity of water in soil, which increases water absorption and provides plants with necessary water. b. it increases the acidity of water in soil leading to the breakdown of rocks in soil. this releases nutrients which can be used by plants. c. it decreases the acidity of water in soil leading to the breakdown of rocks in soil. this releases nutrients which an be used by plants. d. it increases the acidity of water in soil, which decreases water absorption providing plant life with firmer soil for root growth.

b. It increases the acidity of water in soil leading to the breakdown of rocks in soil. This releases nutrients which can be used by plants.

Explanation:  

Some of the soil microorganisms works in the anaerobic conditions to conduct the process of decomposition. They will produce carbon dioxide. The carbon dioxide abundance in the soil will make the underground water acidic. The increase in acidity will promote the breakage of the rocks which will further allow the mixing of the inorganic  minerals particles with the soil aggregates. Therefore, the abundance of carbon dioxide in soil will maintain the balance of organic and inorganic minerals in the soil which are necessary for the growth of plants.
