Question

What are three physical defenses (adaptations) to not being eaten?

Answer 1

Plants have several physical defenses to avoid being eaten including bark, thorns, and toxins.

Step-by-step explanation:

Plants have several physical defenses to avoid being eaten:

1. Bark and waxy cuticle provide an intact and impenetrable barrier, protecting against predators.
2. Thorns and spines are modified branches and leaves that cause physical damage and induce rashes and allergic reactions, discouraging animals from eating the plant.
3. If the first line of defense is breached, plants resort to toxins and enzymes as a second line of defense.

This combination of physical adaptations allows plants to survive and deter predators.
