Which of the following is an example of a non-target organism that could be affected by pesticide application?

The correct choice highlights the importance of understanding the impact of pesticide applications on non-target organisms, which are species that are not intended to be affected by the pesticide. In this context, beneficial insects play a critical role in the ecosystem, such as pollinators like bees or natural pest controllers like ladybugs. These insects provide significant environmental services, and their populations can be severely impacted by pesticide use, leading to unintended ecological consequences.

While weeds, flowers, and grass may be treated with pesticides intentionally or inadvertently, these targets are typically included in pest management strategies. Weeds are the focus of herbicides, while flowers and grass may be treated for various insect and disease issues. However, beneficial insects often fall outside the intended scope of pesticide applications, making them vulnerable to the harmful effects of chemicals designed to eliminate other plant or pest species. Thus, understanding and protecting beneficial insects is essential for promoting sustainable practices in landscape and maintenance work.
