Question

Nutrient cycling is an ecosystem service that maintains soil fertility for agriculture. Which organisms are primarily responsible for this process?

Options

• Predatory insects controlling crop pests

• Pollinators such as bees and butterflies

• Decomposers recycling nitrogen and carbon

• Root systems of tall trees

Answer 1

Nutrient cycling is performed by decomposers that break down organic matter and recycle essential elements like nitrogen and carbon back into the soil. This maintains soil fertility, which is crucial for agricultural productivity.
