Question

how do plants help prevent erosion?
plant leaves are used to create fabrics and other materials.
plant roots help to hold soil in place.
plant leaves take in carbon dioxide during photosynthesis.
plant roots absorb water from the ground.

Explanation:

To determine how plants prevent erosion, we analyze each option:

• "Plant leaves are used to create fabrics..." is about plant use for materials, not erosion prevention.
• "Plant roots help to hold soil in place" directly relates to preventing erosion (erosion involves soil displacement; roots stabilizing soil stops this).
• "Plant leaves take in carbon dioxide..." is about photosynthesis, not erosion.
• "Plant roots absorb water..." is about water uptake, not erosion prevention.

Answer:

B. Plant roots help to hold soil in place.
