54. Prairie ecosystems are common within continental interiors in the northern hemisphere. These ecosystems have a thick, nutrient-rich topsoil and are dominated by grasslands and shrubs. The nutrient-rich topsoil places these regions in high demand for agriculture.What would have a negative impact on biodiversity in a prairie ecosystem?
Answer: D
An increase in the demand for agricultural products as a result of an increase in human population would have a negative impact on biodiversity in a prairie ecosystem.
The increased demand for agricultural products due to a growing human population can lead to intensified farming practices, which often result in habitat destruction, soil degradation, and a reduction in plant and animal diversity within prairie ecosystems.
A) An increase in the use of sustainable technologies in prairie habitats
This option is incorrect as the implementation of sustainable technologies would generally promote biodiversity rather than harm it. Sustainable practices often enhance ecosystem health by minimizing negative environmental impacts and preserving habitats.
B) A decrease in demand for agricultural products as a result of a decrease in human population
This option is also incorrect because a decrease in agricultural demand would likely lead to less intensive farming practices and potentially allow for the recovery of natural habitats, thereby positively impacting biodiversity.
C) An expansion in prairie habitats due to a habitat restoration project
This choice is incorrect as habitat restoration projects are designed to enhance biodiversity by rehabilitating degraded areas and promoting the growth of native species, thus benefiting the ecosystem.
D) An increase in the demand for agricultural products as a result of an increase in human population
This option is correct, as higher agricultural demand can lead to overexploitation of land and resources, resulting in habitat loss and a decline in biodiversity within prairie ecosystems.
Conclusion
The correct answer highlights the detrimental effects of increased agricultural demand on prairie biodiversity, while other options either promote ecological health or do not directly impact biodiversity negatively. Therefore, understanding the balance between agricultural practices and ecosystem preservation is essential for maintaining biodiversity in prairie environments.
