Final answer:
Human construction projects in a natural area can result in decreased habitat size and increased resource availability.
Step-by-step explanation:
The two changes that would be expected as a result of human construction projects in a natural area are decreased habitat size and increased resource availability.
When humans construct buildings or roads, they often destroy or fragment natural habitats, reducing the available space for wildlife to live. This can lead to a decrease in the overall size of the habitat.
However, human construction projects can also create new resources or modify existing ones, leading to an increase in resource availability for certain organisms. For example, the construction of a pond or artificial reservoir can provide new water sources for aquatic species.
