What are millets? why they called coarse grain? give some examples of areas they are grown in.

Millets are cereal crops and small seed grasses, which are widely used in African and Asian countries. Since ages, these small crops were used for human consumption as well as a fodder for animals. Majorly cultivated in the semiarid tropical regions of Africa and Asia, around 97 percent of world’s overall millet production happens in these regions. These have often been called the coarse grains; however, due to their nutritional contributions, these are now being referred as 'nutria-millets/nutria-cereals'. Today, foxtail millet is grown primarily in eastern Asia. Proso millet is grown in the Soviet Union, mainland China, India and western Europe. In the United States, both millets are grown principally in the Dakotas, Colorado and Nebraska.

I hope this helps

fir trees are found in areas with cooler climates. fir trees have needles for leaves and remain green year-round.

it depends on which society you are referring to. many civilization performed rituals so the gods would with their growing season but the most well known is that of the aztecs. they would make sacrifices, usually animals, but sometimes humans as well.
