Question

which of the following does not prevent woody vegetation like shrubs and trees from thriving?

use of pesticides

grazing

fire

drought

Explanation:

To determine which option does NOT prevent woody vegetation from thriving, we analyze each:

• Use of pesticides: Pesticides target pests, not directly preventing woody plants (shrubs/trees) from growing; they may even protect them from pests.
• Grazing: Herbivores eating young shoots/seedlings limits woody plant growth.
• Fire: Can damage or kill woody plants, especially if frequent.
• Drought: Lack of water stresses woody plants, hindering growth.

So, pesticides do not prevent woody vegetation from thriving.

Answer:

A. Use of pesticides
