C  The percentage of humus in the soil will decrease.

Explanation:

The percentage of the humus in the soil will decrease if the decomposers that livers in the field dies.

Decomposers are organisms that breaks down organic matter in nature. They are usually a group of micro-organisms that feeds on dead plant and animal matter.

  • Decomposers reduce dead organisms and plant matter into organic matter.
  • Soil is made up of soil air, organic matter, water and rock materials.
  • Soil organic matter is in form of humus in the soil.
  • When decomposers are no longer available in the soil, the organic matter diminishes.
  • The soil will therefore lack humus.
