- Australia's native plants and animals adapted to life on an isolated continent over millions of years.
- Since European settlement, they have had to compete with a range of introduced animals for habitat, food, and shelter.
- Some have also had to face new predators.
- These new pressures have also caused a major impact on our country's soil, waterways, and native plants and animals.

## Answer

1. Australia's native plants and animals adapted to life on an isolated continent over millions of years.
2. Since European settlement, they have had to compete with a range of introduced animals for habitat, food, and shelter.
3. Some have also had to face new predators.
4. These new pressures have also caused a major impact on our country's soil, waterways, and native plants and animals.

## Explanation

The sequence follows a logical flow: establishing the original state, introducing the catalyst for change, detailing specific threats, and concluding with the broader environmental consequences.

(Sentence 1): The first sentence highlights how Australia's native plants and animals have uniquely adapted to an isolated environment over millions of years, establishing a foundational context for their evolution. (Sentence 2): The second sentence introduces the challenge posed by European settlement, where native species now compete with introduced animals for essential resources, such as habitat and food. (Sentence 3): The third sentence explains that some native species face new predators, adding to the pressure on their survival. (Sentence 4): Finally, the last sentence summarizes the broader environmental impacts of these changes, affecting soil, waterways, and the overall ecosystem, completing the narrative of disruption and adaptation.

## Hints

- Start by finding the sentence that introduces the topic of native life before any external changes occurred.
- Look for pronouns like 'they' or 'these' to see which sentences must follow the ones that introduce the subjects.
