Explanation:

Deforestation generally leads to negative environmental effects impacting ecosystems and hydrological cycles:

- Option 2: Decreased biodiversity - Deforestation destroys habitats, causing species displacement and loss.

- Option 3: Increased soil erosion - The removal of trees leads to the loss of soil stability, making it more prone to erosion.

- Option 4: Decreased rainfall - Trees play a crucial role in the water cycle, and deforestation can disrupt precipitation patterns.

- Option 1: Increased groundwater table - This is not a typical result of deforestation. Instead, deforestation can actually result in reduced groundwater levels due to increased runoff and reduced soil absorption. Correct Answer
