Which of the following environmental changes can pose a risk to bee populations?

Climate change poses a significant risk to bee populations due to the profound and wide-reaching impacts it has on their habitats and food sources. Rapid shifts in temperature, changes in precipitation patterns, and increasing frequency of extreme weather events can disrupt the phenology of flowering plants. This means that plants may bloom earlier or later than usual, which can lead to a mismatch between the timing of resource availability for bees and their life cycles.

Additionally, climate change can lead to habitat loss and alteration, which reduces the diversity of flowers available to bees, further impacting their food sources. It also contributes to the spread of pests and diseases that negatively affect bee health. Together, these factors can lead to declines in bee populations, making climate change a critical concern for their survival and the ecosystems that depend on them.
