D. Introducing an invasive species
E. Overgrazing livestock
F. Increase in precipitation

Answer 1

Changes in temperature, removal of natural vegetation, introducing an invasive species, and overgrazing livestock can all lead to desertification.

Step-by-step explanation:

Desertification, the process of land turning into a desert, can be caused by several changes in a biome. The changes that may lead to desertification include:

1. Changes in temperature: Extreme temperature changes, such as long periods of drought or excessive heat, can cause soil to become dry and barren, leading to desertification.
2. Removal of natural vegetation: When natural vegetation is removed due to deforestation or overexploitation, it exposes the soil to erosion, making it vulnerable to desertification.
3. Introducing an invasive species: Invasive species can disrupt the balance of an ecosystem, outcompeting native plants and depleting water resources, ultimately contributing to desertification.
4. Overgrazing livestock: When livestock graze excessively, they can remove vegetation faster than it can regrow, resulting in soil erosion and desertification.
