Sure, let's break down the simulation for year 5 and year 10 based on natural selection principles. **Year 5:** 1. **Starting Population:** 2,500 organisms. 2. **Harmful Traits:** Some individuals have harmful traits, but they reproduce at a lower rate. 3. **Neutral/Beneficial Traits:** These individuals reproduce at a higher rate. **Simulation for Year 5:** - **Harmful Traits:** Assume a reduction due to lower reproductive success. Let's say 15% of the population has harmful traits. - 2,500 * 0.15 = 375 organisms with harmful traits. - **Neutral/Beneficial Traits:** The remaining population will have neutral or beneficial traits. - 2,500 - 375 = 2,125 organisms with neutral/beneficial traits. **Year 10:** 1. **Starting Population:** 2,500 organisms. 2. **Harmful Traits:** Continue to decrease. 3. **Neutral/Beneficial Traits:** Continue to increase. **Simulation for Year 10:** - **Harmful Traits:** Further reduction. Let's say harmful traits now account for 5% of the population. - 2,500 * 0.05 = 125 organisms with harmful traits. - **Neutral/Beneficial Traits:** The remaining population will have neutral or beneficial traits. - 2,500 - 125 = 2,375 organisms with neutral/beneficial traits. **Justification:** - **Natural Selection:** Over time, individuals with harmful traits have a lower reproductive success rate, leading to a decrease in their proportion within the population. - **Trait Distribution:** Beneficial and neutral traits become more prevalent as they contribute to higher reproductive success. **Diagram:** For Year 5 and Year 10, you can draw two bar graphs or pie charts: - **Year 5:** - Harmful Traits: 375 - Neutral/Beneficial Traits: 2,125 - **Year 10:** - Harmful Traits: 125 - Neutral/Beneficial Traits: 2,375 Label each section clearly to show the distribution of traits within the population at each time point.
