Question

What are weeds?

Answer 1

Hint: These are undesirable and unwanted plants that grow on their own. These are specifically found in gardens, farm fields etc.

Complete answer:
Weeds are “plants at the wrong place”. These do not have any biological importance. Plants that start to grow on their own can be called a weed for example where one species of plant might be valuable and others can be harmful as it grows on its own.
Weeds can also be plants that reproduce more aggressively than native plants. Specifically, weeds are plants that reproduce quickly and can survive in adverse conditions.
Weeds are harmful in following ways:
1. These compete for habitat, light, water and other resources.
2. They can cause damage to the roots of plants and lead to stunted growth.
3. They provide a place for hosts and vectors giving a chance to destroy desired plants.
4. These usually give allergy or irritation to skin or digestive tract of animals
Sometimes weeds are beneficial in some ways.
1. Some weeds are used as food.
2. Some weeds are helpful in treating diseases and act as medicine.
3. They also help in increasing the fertility by absorbing nitrogen and calcium.
4. Sometimes they help in avoiding pests from main plants.as pests get distracted and feed on them rather than desired plants.

Note:
The process of removing weeds is called weeding. Weeding is done with the help of weedicides. This is done before planting or flowering so avoid competition for habitat, niche etc.
