Question

Which of these is the major function of bacteria and fungi in an ecosystem?

• A. Absorption of inorganic nutrients
• B. Degradation of inorganic matter
• C. Degradation of organic matter
• D. Fixation of nitrogen and phosphorus

Answer 1

The correct option is C Degradation of organic matter

Decomposers (bacteria and fungi) are the waste managers of any ecosystem. They are the final link in a food web breaking down dead organic matter from producers and consumers. The decomposition results in simple inorganic molecules which are returned to the soil.
