Q. Why Are Earthworms Important?
Here are the reasons why earthworms are useful:
- Earthworms play a vital role in accelerating the decomposition of organic matter and fertilizing the soil by constantly eating and excreting out. This makes the soil rich in nutrients that are beneficial for plants.
- They are considered to be great soil engineers as they loosen and mix the soil up by moving through it by aerating the soil and promoting drainage. By drawing organic material into their burrow, earthworms make the soil more fertile and helpful in preventing erosion and flooding.
- As earthworms are very sensitive to pollutants like unwanted heavy metals, pesticide residues, they are used for assessing the impact of various pollutants and land usage.
- They can help in repairing damaged soil and can provide solutions to man-made problems. They could help to clean up lands contaminated with hazardous, toxic heavy metals like lead.
- They are the important food source of a large variety of birds and other animals.
