Answer 1

1. To prevent landslides in sloping areas on mountains we can make terraces so that the slopes can absorb more water and not cause landslides.

2. The life cycle of grasshoppers that harms humans is the stage of adult animals (imago). Adult grasshoppers can become agricultural pests because they are herbivores. If the population is excessive, they can damage agricultural crops and harm farmers.
