Which of the following organisms do not play a role in increasing soil fertility?
Caterpillars
Soil fertility is naturally maintained by the microorganisms like bacteria and fungi residing in the soil. Besides these, other organisms like algae, termites, and earthworms also replenish the soil with essential nutrients, thereby helping the plants to grow well. Caterpillars play no role in soil fertility. They are considered as pests as they eat up plant leaves.
