Description: Plants cannot hide their leaves. They need to protect them from herbivores such as caterpillars. But how do the caterpillars protect themselves from their predators? We can see two ways here. First, the caterpillar is eating the leaf from the underside. Second, the caterpillar has distasteful spikes. The food chain is a complex cascade of adaptations.
