- Statement I is false but Statement II is true
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Crop-weed competition occurs for resources.
Mobility and resource requirements affect competition.
Step 2: Key Formula or Approach:
No specific formula.
Need to understand competition dynamics.
Step 3: Detailed Explanation:
Statement I: Due to lack of mobility, competition is active and visible at the beginning.
This is true.
Statement II: A good competitor is the species with least resource requirement.
This is false.
A good competitor is the species that can acquire resources efficiently.
It is not about having the least requirement.
Thus, Statement I is true, but Statement II is false.
Step 4: Final Answer:
Statement I is true but Statement II is false.
Hence, the correct option is (C).
Crop-weed competition occurs for resources.
Mobility and resource requirements affect competition.
Step 2: Key Formula or Approach:
No specific formula.

Step 3: Detailed Explanation:
Statement I: Due to lack of mobility, competition is active and visible at the beginning.
This is true.
Statement II: A good competitor is the species with least resource requirement.
This is false.
A good competitor is the species that can acquire resources efficiently.

Thus, Statement I is true, but Statement II is false.
Step 4: Final Answer:
Statement I is true but Statement II is false.
Hence, the correct option is (C).

- Given below are two statements:
Statement (I): The combined effect of competition and allelopathy where growth of weeds or crop or both is reduced is called allelomediation.
