Give reasons for the following:

Explanation

### Step-by-Step Solution:

1. **Introduction to Earthworms**: Earthworms are small, segmented worms that live in the soil. They play a crucial role in the ecosystem, particularly in agriculture.

2. **Soil Aeration**: One of the primary reasons earthworms are considered friends of farmers is that they burrow through the soil. This burrowing action helps to aerate the soil, allowing air to reach the roots of plants. Proper aeration is essential for healthy plant growth.

3. **Nutrient Recycling**: Earthworms consume organic matter, such as dead leaves and plant material. As they digest this material, they break it down into simpler forms, which are then returned to the soil as nutrient-rich castings. These castings are a natural fertilizer that enhances soil fertility.
