Do not spend time restating the questions or providing more than the number of examples called for.  \nA calculator is available in this application and can be accessed throughout the exam.  \nFor the parts of question 3 where calculations are required, clearly show how you arrived at your answer. You do not need to include units unless indicated. Use your keyboard for the following math expressions and symbols:  \n• Multiplication: use an “x” or asterisk (*) Example: 4 x 5 or 4 * 5  \n• Division and Fractions: use a forward slash ( / ) Example: 17 / 5  \n• Degrees: write “degrees”Example: 25 degrees C  \n• Grouping: use parentheses Example: (2+3) / (7-5)  \nWithin the application, you can enter subscript or superscript, but the following methods are also acceptable:  \n• Subscript: use an underscore ( _ ) Example: CO_2  \n• Superscript: use a caret (^) Example: 10^12  \nYou may pace yourself as you answer the questions in this section, or you may use these optional timing recommendations:  \nThe suggested time is about 22 minutes for each question.  \nYou may use the available paper for scratch work, but credit will only be given for responses entered in this application. Text you enter as an annotation will not be included as part of your answer. For questions that have sub-parts, be sure to label those clearly in your answer.  \nYou can go back and forth between questions in this section until time expires. The clock will turn red when 5 minutes remain—the proctor will not give you any time updates or warnings.  \nNote: This exam was originally administered digitally. It is presented here in a format optimized for teacher and student use in the classroom.  \n© 2025 College Board.  \n[Visit College Board on the web:](Visit College Board on the web: collegeboard.org 2)[ collegeboard.org](Visit College Board on the web: collegeboard.org 2)[ 2](Visit College Board on the web: collegeboard.org 2)  \nAP ENVIRONMENTAL SCIENCE 2025 n FREE-RESPONSE QUESTIONS  \nChickadees are a K-selected species of bird that eat insects and spiders. Spiders consume insects, and many insects consume plants as shown in the following food chain.  \nPlants → Insects → Spiders  \nChickadee habitat includes forests and residential yards. Residential yards often contain nonnative plants, which do not naturally exist in an area, but were introduced by humans. Scientists measured the average number of insects and spiders as related to the percentage of nonnative plants (Figure 1) . The scientists also measured the chickadees’ average population growth rate (Figure 2) to determine the impact of nonnative plants on chickadee populations.  \nFigure 1.
