Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of resources that influence competition between weeds and crops.
Step 2: Detailed Explanation:
Phosphorus is a nutrient resource that influences competition in a weed-crop environment.
Weeds and crops compete for nutrients like phosphorus.
pH (A), Bulk density (B), and Water holding capacity (C) are soil properties, not resources.
They influence resource availability but are not resources themselves.
Thus, phosphorus is a resource influencing competition.
Step 3: Final Answer:
Thus, phosphorus causes a 'resource' influencing competition, which corresponds to option (D).
