Question

Weeds affect the crop plants by

• B. Dominating the plants to grow
• C. Competing for various resources of crops causing low availability of nutrients
• D. All of the above

Answer 1

Answer: (C)

Competing for various resources of crops causing low availability of nutrients

Weeds are nothing but unwanted crops that grow along with the main crop. Thus, they compete with the main crop for sunlight, water, nutrients, and space and thus reduce the resources available to them. In this way, they hamper the growth of the main crop.

So, option C is the correct answer.
