ii)
The process of growing a seed into a well being
crop for taking vegetables, fruits and grains from it is called agriculture.
12)i)
Cultivating a particular soil repeatedly turns that soil polluted and not being any nutrients. That's why we should not use it repeatedly.
Example- Suppose I have two particular lands.
I should use one of it for agriculture for one year. Then I can tell that all the nutrients from that particular soil has been used. So to generate nutrients again we have to cover that field by manure. It can bring the nutrients back.
So for next one year I will carry this process of giving manure again and again. In this next year I will carry agriculture on the other field.
This entire process is called crop rotation.
ii)
Weeds which grow during crop cultivation takes all the nutrients from the crops.
That is why Weeds should be removed.
