Are some weeds useful? Please name some weeds and describe their use.
Yes, some weeds are useful. Bermuda grass (Haral in Marathi) is used in playgrounds, sports fields, and high-traffic areas because it is highly tolerant to heat and drought. It also provides habitat and food for various insects and wildlife species. Some weeds have medicinal properties and are used in traditional medicine. Weeds can also help prevent soil erosion and add organic matter to the soil when they decompose.
Explanation
The chapter provides an example in Table 2.6 showing that Bermuda grass, though a weed, has uses in playgrounds and sports fields. It is highly tolerant to heat and drought and provides habitat and food for insects and wildlife. This demonstrates that weeds can have beneficial uses despite being harmful to crops.
