How being an annual plant helps a weed to live in its habitat?

Being an annual plant allows a weed to complete its life cycle in a single growing season, enabling it to quickly reproduce and spread before environmental conditions become less favorable. This rapid life cycle helps it exploit available resources, such as sunlight, water, and nutrients, effectively outcompeting slower-growing plants. Additionally, annual weeds can produce a large number of seeds, ensuring their persistence in the habitat even if the parent plants die off due to adverse conditions. This adaptability enhances their survival and dominance in disturbed or competitive environments.
