Question
**Question 17:** A fruit fly that has a short life span, produces many offspring, and spends little energy raising their young can be classified into which reproductive strategy? A. *r*-strategist B. a carrying-capacity strategist C. *k*-strategist D. a logistic strategist **Explanation:** This question relates to ecological reproductive strategies. Organisms classified as *r*-strategists typically have short lifespans, produce many offspring, and invest minimal energy in raising them. *K*-strategists usually have longer lifespans, produce fewer offspring, and invest more energy in parental care.

### Honeybee Population Decline **Context:** The decline in both domesticated and wild bee populations is a critical issue affecting ecosystems and agriculture globally. According to scientists, the main factors contributing to this decline include diseases spread by mites and other parasites, as well as the extensive use of pesticides on crops. **Source:** “Bee Declines May Spell End of Some Fruits, Vegetables,” *National Geographic News*, October 5, 2005. **Discussion:** Conservation biologist Claire Kremen from Princeton University emphasizes the importance of taking action to slow the decline of domesticated honeybees and support wild bee populations. Without intervention, the disappearance of bees could lead to a significant reduction in the availability of many fruits and vegetables. ### Key Questions: **14. What is partly responsible for the decrease in the honeybee population?** A. The use of pesticides B. The use of fertilizers C. A decrease in prey D. A decrease in fruits and vegetables **Answer:** A. The use of pesticides **Explanation:** The use of pesticides is identified as a key factor in the decline of honeybee populations. Pesticides can have harmful effects on bees, contributing to colony collapse and population decline.
