What is one way healthy trees can resist pest attacks?

Healthy trees can resist pest attacks through enhanced health and vigor. When trees are in good condition, they possess stronger biological defenses, enabling them to fend off pest invasions more effectively. Healthy trees typically have robust leaves, bark, and root systems that can better withstand physical damage and stress. This strength allows them to respond to pest threats through various natural mechanisms, such as producing secondary metabolites that deter pests or attract beneficial organisms.

The options that suggest weakened growth or providing better habitat for pests do not support tree health and resistance to pests. Similarly, while chemical repellents can be an effective management strategy, relying on them does not reflect the inherent capabilities of healthy trees. The emphasis on enhanced health and vigor highlights the natural resilience that trees exhibit, which is essential for their survival in ecosystems often challenged by various pest pressures.
