Here are the answers to each of the questions provided:

1. **Which of these is a disturbance that would trigger primary succession?**
- **Answer:** glacial retreat
(Primary succession occurs in lifeless areas where soil has not yet formed, such as after glacial retreat.)

2. **Which types of plants are most likely to grow first after an area has been cleared for road construction?**
- **Answer:** grasses
(Grasses are typically among the first plants to colonize disturbed areas as they can quickly establish and spread.)

3. **Only rocks are left once a glacier retreats. What types of plants are likely to arrive in the area first?**
- **Answer:** lichens and mosses
(Lichens and mosses are pioneer species that can grow on bare rock and are crucial in the early stages of primary succession.)

4. **A student drew a food web. One path includes plants, a mouse, a rabbit, and an owl. Which population of organisms has the most energy?**
- **Answer:** grass
(In a food web, energy is highest at the producer level, which is grass in this case.)

5. **Which of these models most clearly explains that producers in a food web have more energy than consumers?**
- **Answer:** energy pyramid
(An energy pyramid visually represents the energy transfer between trophic levels, illustrating that producers have the most energy, with each successive level having less energy.)
