Final answer:
Farmers create drought-resistant seeds, use agricultural chemicals, and fix machinery when it breaks down.
Step-by-step explanation:
Farmers are often the ones who create different kinds of seeds to withstand drought. They use selective breeding techniques to develop plants with traits that are more resistant to dry conditions. This helps to ensure that their crops can survive and thrive even when faced with limited water availability.
While farmers may not necessarily be chemical engineers, they do use various agricultural chemicals, such as fertilizers and pesticides, to protect their crops from pests and diseases. They apply these chemicals with the aim of maximizing crop yield and minimizing damage caused by insects, weeds, and fungi.
Another important role that farmers take on is fixing machinery when it breaks down. They need to have a good understanding of the equipment they use, such as tractors and irrigation systems, in order to maintain and repair them when necessary.
