Final answer:
Human construction projects can result in decreased habitat size and increased resource availability in natural areas.
Step-by-step explanation:
Two changes that can be expected as a result of human construction projects in a natural area are decreased habitat size and increased resource availability. Construction projects often involve clearing land and altering the natural landscape, which can reduce the overall size of available habitat for plants and animals. Additionally, the construction process may create new resources or make existing resources more accessible, leading to an increase in resource availability for certain species.
