Abiotic factors are best described as:

Abiotic factors are best described as:

• A. Living organisms that influence pests
• B. Non-living environmental controls
• C. Pest biology
• D. Pest population dynamics

Answer: (B)

Abiotic factors are non-living environmental conditions that influence how pests survive, develop, and behave. These include temperature, humidity, light, rainfall, soil type and moisture, pH, and wind. They shape where pests can thrive and how quickly they grow or reproduce. For example, many insects need a specific temperature range to develop; too hot or too cold can slow or stop their life cycles. Humidity and rainfall can affect egg viability or disease in pests, while soil conditions influence root-feeding pests. These factors are about the environment itself, not living organisms. The other descriptions refer to living things or processes. Living organisms that influence pests describe biotic factors, not abiotic. Pest biology focuses on the pest’s own life processes, while pest population dynamics looks at how pest numbers change over time, which can be driven by many factors, including abiotic ones, but isn’t itself the environmental factor.
