Hydro electricity is derived from water, wind energy from air and the rest are derived from land.

Raw materials from could also include crude oild extracted from the sea beds. 

Land is of no use without human efforts and other factors of production.Hence, the land is a passive factor of production.

Primary sector of an economy deals with the production of raw materials and basic foods. Examples of primary sector are: agriculture, mining, forestry, etc. Under-developed countries mainly depends on primary activities for the employment opportunities.

The basic factors of production are Land, Labour, Capital and entrepreneur. 

More the natural resource a country has ,more prosperous it becomes.As the per capita resource gets increased,production increases and hence the economy gets richer.

Improved seeds(HYV seeds), chemical manures and machines(like tractors,improved irrigation facilities) assist in maximizing the productivity of land, since they would bring in efficiency in the production process.

Productivity of land refers to the total output divided by the per unit area of land.Hence the productivity of land is measured to check the extent of efficiency.

Fertility of land is one of the factor which is responsible for measuring the productivity of land. More fertile the land is, more will be the production of crops (output).

Sometimes the State is unable to improve the conditions of agricultural sector. Proper investment in this area is often neglected by the state. Hence, the State's negligence towards agriculture can result in low productivity of land which will result the economy to fall in an low equilibrium trap.

More efficient the land gets used in an economy,more the economy gets developed and rich. Hence the land influences the economic growth of a country.

Land maintains the ecological balance. Ecology is the science of the study of ecosystems. Ecological balance is a state of equilibrium where all the species live in harmony.

Water resources close to farm lands is essential for better productivity due to better irrigation. This s especially important in under developed and developing countries as they lack infrastructure to for proper irrigation facilities. 

The skills and the competence of the farmers is proved to directly increase the productivity of the land under cultivation. This is because a skilled and competent labour force is necessary to optimally use the inputs from land to maximise output.

Improved techniques used in the production system ,increases the ability of the land to generate more goods and services in a more efficient and effective way.

Quasi-rent refers to the excess amount earned from the utilization of land for the production mechanism during short period of time.

Land is a free gift of nature and it is fixed in terms of the area hence it is the most scarce resource among the following.

It is a final consumption as over here the residential tenant is the final consumer. Moreover, paying rent to the owner does not involve any  intermediate consumption.

The cost of land as factor of production is known as rent.For instance, when a person utilize a piece of land for any production purpose,certain cost in the form of rent is to be paid.

Complete mobility is not a characteristics of land as land is a free gift of nature ,it does not possess any mobility ,that is, it cannot be moved from one place to another.

Coal mines of Bihar, water resources of Uttaranchal,mineral deposits of Jharkhand- all these resources are regarded as land in economics because these resource help to produce goods and services in the economy thus, an efficient production process can be ensured. Income and employment generation -can also be increased by utilizing these resources.

Land has a flat supply curve since the quantity supplied of land is fixed since land is a natural resource. Therefore, the supply curve of land is inelastic in nature, that is, supply of land remains fixed irrespective of the change in demand level.

Land is a natural resource and does not possess any mobility ,that is ,it cannot be moved from one place to another.

Among the 4 factors of production, land is a free gift of nature to human beings, its quantity supplied is unlimited and fixed.

Land is a passive factor of production,and hence it is dependent on other factors of production like,labour.(human efforts )

Land includes all those natural resources which help in the production process to increase the productivity of an economy.

Land is a free gift of nature to human beings,thus it is not a man-made factor.

Land is not produced by any human, it is a free gift of nature and its quantity supplied is fixed.

Land is not produced by our forefathers.It is a free gift of nature to mankind and thus the quantity supplied of land is fixed form the history of evolution.

Land is a natural resource .It is considered as a free gift of nature to mankind,thus its quantity supplied is fixed.Hence,labour is a man-made factor.

A chemical fertilizer is defined as any inorganic material of wholly or partially synthetic origin that is added to the soil to sustain plant growth. Can also kill bacteria and other micro organisms in the soil.

In agriculture, multiple cropping is the practice of growing two or more crops in the same piece of land during a single growing season. It is a form of polyculture.

Bigha and Guintha are two local units of measuring land area in village.

Haryana state was the first to try out modern farming methods in India.

Fixed capital includes the assets that are needed to start up and conduct business. These assets are considered fixed as they are not consumed or destroyed during the actual production of a good or service but have a reusable value. 

Working capital is the daily expenses which a business bears. Machines are fixed capital. 

Working capital is the daily expenses which a business bears

In agriculture, multiple cropping is the practice of growing two or more crops in the same piece of land during a single growing season. It is a form of polyculture. 

The above is true because land depletes in resources over time and takes time to replenish itself. 

Products of land includes anything that is obtained or created by the land. 

Land is used for various purposes in the production process such as cultivation of land is undertaken to generate agricultural produce, setting up of dairy or poultry farms, sheep rearing, industrial plants and factories, etc.

As Marshall said, "By land is meant not merely land in the strict sense of the world, but whole of the materials and forces which nature gives freely for man's aid in land and water, in air, light and heat". Hence, all of the above. 

Land has been defined by Prof. Marshall as, "By land is meant not merely land in the strict sense of the word, but whole of the materials and forces which nature gives freely for man's aid in land and water, in air, light and heat".

Land is the basic basis of transportation because of its extreme importance. It can provide door to door services; cost of land transportation is reasonable; less chance of the goods to get damaged ,etc

Land is a natural resource. It is a free gift of nature to mankind. Because of the presence of land our subsistence, residence and other necessities of life is facilitated.

Land ownership laws determines that 'who will own the land' ,has an extreme significance on the productivity of the land ,that is, the ability to produce goods and services in an economy in a more efficient and effective manner.

The farmers will not look to improve land productivity or maintain the land in good condition as insecurity of tenancy rights will demotivate them to do so. 

Capital is the fundamental factor that affects the productivity of land as for production capital is needed.For example, for cultivating the land proper HYV seeds,agricultural facilities,etc is needed- to facilitate all these capital is of extreme significance.

Water resources close to farm lands is essential for better productivity due to better irrigation. This s especially important in under developed and developing countries as they lack infrastructure for proper irrigation facilities. 

Calculation of average productivity of land helps us to understand the per unit land productivity, which helps us to know the ability of a production system to produce more effectively and efficiently.

Land is one of the four basic factors of production. 

Land alone is of no use without human resource or efficient and effective labour resource. An efficient production mechanism is established with the proper coordination between land and labour, where in the labour makes use of the land to produce output.

The reward for land is rent. Thus if the land is not owned by the entrepreneur the owner of the land must be compensated for its usage and thus the entrepreneur pays rent. 

This happens due to negative marginal returns for eg , in case of excessive employment in a particular land. At this point withdrawal of workers will help to increase the total output.

Land is a free gift of nature to the human beings hence the supply of land is fixed,it requires labours and capital to be useful in order to make some production to the economy, it does not possess an mobilty,ie, it cannot be moved from one place to another.

Land has a flat supply curve because the quantity supplied of the land is fixed as land is natural resource. Land has a perfectly inelastic supply, that is, the supply of the land remains fixed irrespective of the increase or decrease in the demand of the land.

Supply of land is perfectly inelastic as change in demand of land does not lead to any change in supply of land as land is a free gift of nature and it's quantity is fixed.Supply curve of land is a straight vertical line .

The supply of land is fixed as land is a free gift of nature,it can neither be increased,decreased nor it is unlimited.

India is the seventh largest country in the world on the basis of its land area. The share of India in percent terms is only 2.4 per cent of the total land surface of the world.

Rent, for a land in the case of cultivation land, refers to the difference between the value of the produce and the cost of cultivation. Marginal land is the last grade of land cultivated whose price of produce is just equal to the cost incurred. Thus, it is a rent-less land, since the cost of cultivation is equal to the value of the produce.

The introduction of high-yielding varieties of seeds led to the increase in production of foodgrains, thus improving agriculture in India.

Dairy farming is a non-farm activity.

The kharif crops include rice, maize, sorghum, pearl millet/bajra, finger millet/ragi (cereals), arhar (pulses), soyabean, groundnut (oilseeds), cotton etc. 

The above statement is true as land is a free gift of nature.Its supply is fixed and limited in area.

Marshall said, "By land is meant not merely land in the strict sense of the world, but whole of the materials and forces which nature gives freely for man's aid in land and water, in air, light and heat"

TRUE,as land is a free gift of nature to human beings so that humans can utilize land for the production process.Hence the man did not pay any price for the acquired land .At that time concept of private property was also not there.

Fertility of land depends upon various factors but mainly on the climatic conditions,rainfall etc.Hence the fertility of land varies from places to places.

Minerals are formed from the decomposition of soil.The decomposition of soil occurs due to climatic conditions of that particular area.Hence the richness of mineral wealth varies from place to place.
