Option 1: Forests protect the soil from erosion. This statement is correct. Forests act as a natural barrier, preventing the force of rain and wind from directly impacting the soil. The roots of trees and vegetation hold the soil in place, reducing the risk of erosion.

Option 2: Plants and animals in a forest are not dependent on one another. This statement is incorrect. Plants and animals have a mutual dependency in a forest ecosystem. Plants provide food and shelter for animals, while animals aid in pollination and seed dispersal for the plants. They rely on each other for survival.

Option 3: Forests influence the climate and water cycle. This statement is correct. Forests play a crucial role in regulating temperature, humidity, and rainfall patterns. They release moisture through transpiration, which in turn affects local and regional climate conditions and contributes to the water cycle.

Option 4: Soil helps forests to grow and regenerate. This statement is correct. Soil provides essential nutrients, water retention, and anchoring support for tree roots. Without fertile and healthy soil, forests would struggle to grow and regenerate.

Therefore, the correct answer is option 2.
