The correct answer is bacteria. Bacteria abundant in soil is the main source of its organic matter. This is because bacteria release energy in their systems which causes the soil to be more fertile and more capable of sustaining plant material. Without bacteria general processes of soil formation will not be possible.

Answer:
Silent mutations do not affect protein function
Explanation:
A mutation is defined as any alteration in the genetic material of a cell of a living organism. Moreover, a silent mutation refers to any mutation that does not alter the phenotype of the cell/organism (they are evolutionary neutral mutations). Silent mutations are base substitutions that do not alter the amino acid sequence of the resulting protein, and therefore these mutations do not alter protein function.
