Which of the following describes an unwanted organism impacting human activities directly?

• A. Aquatic pest
• B. Beneficial organism
• C. Resource manager
• D. Native wildlife

Answer: (A)

The term used to describe an unwanted organism that adversely impacts human activities is "aquatic pest." Aquatic pests can include invasive species like certain types of weeds, fish, or invertebrates that disrupt ecosystems, hinder recreational activities, damage infrastructure, or negatively affect the economy, particularly in sectors like fishing and tourism. By definition, these organisms are not just inconvenient but can also pose significant challenges that require management strategies to mitigate their impact. The other options represent categories that do not fit the description of a harmful organism. Beneficial organisms typically contribute positively to the ecosystem or human activities, such as providing services like pest control or pollination. Resource managers are professionals responsible for overseeing and maintaining the health of natural resources and do not describe an organism. Native wildlife refers to species that are originally found in a certain area and play vital roles in that ecosystem; while they can have impacts, they are not typically classified as unwanted organisms impacting human activities adversely in the same way aquatic pests are.
