Which of the following is an environmental factor that can affect bee health?

Pesticides are a significant environmental factor that can affect bee health because they contain chemicals that can be harmful or even lethal to bees. Exposure to pesticides can lead to a range of negative effects, including disorientation, reduced foraging ability, impaired reproduction, and increased mortality rates. Understanding the impact of pesticides is crucial for beekeepers and anyone involved in agriculture to ensure that bee populations remain healthy and robust, as bees play a vital role in pollination and the overall health of ecosystems.

Fresh flowers, high temperatures, and sunny weather, while they can influence bee behavior and productivity, do not have the same direct and damaging impact on bee health as pesticides do. Fresh flowers provide essential nectar and pollen, high temperatures may lead to heat stress if managed improperly, and sunny weather generally promotes foraging opportunities. However, none of these factors inherently pose the same level of direct threat to bee populations as pesticide exposure.
