Answers
GPT-4o mini
1. **True** - Matter is recycled in biological systems, and energy flows in and out and cannot be recycled.
2. The water cycle process labeled #4 is called **precipitation**.
3. To help reduce the spread of invasive species, you can:
- **report an invasive species**
- **plant native species**
- **do not take firewood from outside sources to parks and campgrounds**
(Do not select "release unwanted pets into the woods or streams" as this contributes to the spread of invasive species.)
4. Persistent organic pollutants and heavy metals that eventually show up in higher-level consumers at higher concentrations is due to **biomagnification**.
5. Within the ecosystem, the organisms found at the very bottom of the energy pyramid are **producers**.
6. The percentage of energy lost as heat or used for life processes at each step of the trophic pyramid is approximately **90%**, meaning that about **10%** is passed on to the next level.
7. For preparing for the Unit 3 Energy Flow test, resources or activities can vary by individual. Recommendations may include study guides, textbook readings, online resources, practice quizzes, and discussions with peers or instructors.
(Note: Some of the questions were presented in a way that suggested there was a visual component to provide answers, which I can't see. Therefore, the answers provided for those questions rely on common ecological knowledge.)
