- Deserts are dry areas where rainfall is less than 50 centimeters (20 inches) per year.
- They can be either very cold or hot, although most of them are found in subtropical areas.
- Because of their extreme condition, there is not as much biodiversity found in deserts.
- Any vegetation and wildlife living in a desert must have special adaptations for surviving in a dry environment.

## Answer

1. Deserts are dry areas where rainfall is less than 50 centimeters (20 inches) per year.
2. They can be either very cold or hot, although most of them are found in subtropical areas.
3. Because of their extreme condition, there is not as much biodiversity found in deserts.
4. Any vegetation and wildlife living in a desert must have special adaptations for surviving in a dry environment.

## Explanation

The sequence correctly moves from a general definition of the environment to its climatic variations, then to the resulting low biodiversity, and finally to the specific adaptations required for survival.

(Sentence 1): It begins by defining deserts as dry areas with less than 50 centimeters (20 inches) of rainfall per year, establishing a clear understanding of what deserts are. (Sentence 2): The second sentence explains that deserts can be very cold or hot, although most are located in subtropical areas, adding depth to the definition. (Sentence 3): The third sentence notes that deserts have limited biodiversity due to their extreme conditions, indicating the ecological impact of such environments. (Sentence 4): Finally, it highlights that any vegetation and wildlife in deserts must have special adaptations to survive in the dry environment, emphasizing the unique challenges faced by desert organisms.

## Hints

- Start by finding the sentence that defines the subject matter generally.
- Look for pronouns or logical connectors that link the climate description to the biological consequences.
