Hey mate!
Here's your answer!!
◾️ECONOMICS
8) Working capital refers to the people who will do the work. In some sort of work, educated labour is also required.
9) The fullform of HYV seeds is high yielding variety seeds.
10) Dairy farming is included in non farming activities.
11) Farming is the main occupation in the imaginary village of palampur. Almost 75 % of people of the village are engaged in farming. They depend mainly on farm produce. To promote such activities modern methods of irritated and multiple cropping are greatest solutions.
12) Green revolution is the increase in crop production achieved in different countries by using artificial fertilizers, pesticides and HYV seeds.
Two main features:
◾️Introduction of new and high yielding seeds.
◾️Use of latest agricultural machinary and high disease resistant varieties to enhance crop production.
13) Land is a natural resource that supports vegetation, wild and human life, transport and communication and is used for various purposes like agriculture. Some ways to sustain land are:
◾️Soil is a vital part of land, fertilizers have much polluted it. So bio compost and eco friendly methods should be used.
◾️Some farming practises are also helpful in sustaining land. These are multiple cropping, Crop rotation etc.
◾️Modern farming methods should be used to prevent further damage of land.

8. working capital is a money,which we use in business, in exchange of goods and services.
9. the full form of HIV High Yield Variety seeds.
10.Dairy farming is primary activity because we get the milk directly from the cattle.
13.the part of the earth's surface that is not covered by water.
Sustain ways
-Stop deforestation
-Stop land degradation
-Shelter belts
-Terrace farming.
-Reserve the grazing grounds.
