Answer 1

Answer:

Weeds are defined as the unwanted plants in crop fields which grow along with the main crop. They are strong and dominating competitors for crops. Their copious seed production, quick population establishment, and adaptation characteristics make them tough competitors and help in their survival. Common examples of weeds are grass, algae, Amaranthus, Chenopodium.

Weeds compete for essential components required by crops. They compete for light, water, nutrients, and space. They reduce the yield and sometimes they are sources of diseases as well.
