Question

A farmer grows rice crop year after year in his field . He notices a gradual decrease in the yield. What could be its cause?​

Answer 1

Answer:

Agriculture is the art and science of cultivating the soil, growing crops and raising livestock. It includes the preparation of plant and animal products for people to use and their distribution to markets.

Agriculture provides most of the world’s food and fabrics. Cotton, wool, and leather are all agricultural products. Agriculture also provides wood for construction and paper products.

These products, as well as the agricultural methods used, may vary from one part of the world to another.

Start of Agriculture

Over centuries, the growth of agriculture contributed to the rise of civilizations.

Before agriculture became widespread, people spent most of their lives searching for food—hunting wild animals and gathering wild plants. About 11,500 years ago, people gradually learned how to grow cereal and root crops, and settled down to a life based on farming.

By 2,000 years ago, much of the Earth’s population had become dependent on agriculture. Scholars are not sure why this shift to farming took place, but it may have occurred because of climate change.
