In the context of organic chemistry, how does a loss in crop biodiversity affect agricultural practices?
A
It reduces the need for crop rotation and soil management.
B
It results in a greater variety of crops available for cultivation.
C
It enhances the natural resistance of crops to pests and diseases.
D
It leads to increased reliance on chemical fertilizers and pesticides.
Verified step by step guidance1
Understand the concept of crop biodiversity: Crop biodiversity refers to the variety and variability of plant species used in agriculture. High biodiversity can contribute to ecosystem resilience, pest and disease resistance, and soil health.
Consider the impact of reduced biodiversity: When biodiversity is reduced, the natural balance and resilience of the ecosystem are compromised. This can lead to increased vulnerability to pests and diseases.
Analyze the need for chemical inputs: With lower biodiversity, crops may lack natural resistance to pests and diseases, leading to a greater reliance on chemical fertilizers and pesticides to maintain crop yields and health.
Evaluate the role of crop rotation and soil management: High biodiversity often supports practices like crop rotation and soil management, which help maintain soil fertility and reduce pest buildup. Reduced biodiversity can diminish the effectiveness of these practices.
Conclude the implications for agricultural practices: The loss of crop biodiversity typically results in increased dependency on chemical interventions to compensate for the lack of natural ecosystem services, such as pest control and soil fertility maintenance.
