Question

How can excess felling of trees affect ecosystems?

• A. It leads to excessive rainfall.
• B. It improves air quality.
• C. It promotes wildlife conservation.
• D. It reduces biodiversity.

Hint:

Trees regulate rainfall patterns through transpiration; excessive felling disrupts this balance, affecting local climate.

Answer 1

The Correct Option is A

Large-scale tree removal significantly disrupts ecosystems. A primary consequence is the alteration of the water cycle. Trees facilitate transpiration, a process where water absorbed by roots is released as vapor from leaves, contributing to cloud formation and precipitation. Extensive deforestation imbalances this vapor release, potentially causing erratic rainfall, including localized downpours.
However, deforestation generally leads to a reduction in local rainfall due to diminished transpiration. Yet, microclimate shifts can trigger irregular or intense precipitation. Furthermore, excessive logging results in soil erosion, habitat destruction, and a decline in biodiversity.
