Many pesticides that farmers applied to their crops are eventually washed away by the rain and end up in ponds or other bodies of water where amphibians live. Amphibians are especially vulnerable to pesticides dissolved in the water because of their moist skins. Water can pass through an amphibian’s skin allowing toxins dissolved in the water to enter the amphibian’s body.
Q: According to the speaker, why do pesticides pose a threat to amphibians?
- Pesticides can cause an amphibian's skin to dry out.
- Pesticides kill the insects that amphibians depend on for food.
- Dissolved pesticides can easily enter amphibian's bodies.
