Subsistence Farming: When farming is done to meet the needs of the farmer’s family, it is called subsistence farming. In subsistence farming, low levels of technology and household labour are generally utilised. Farming is done on smaller plots and output is also small. Subsistence farming can be further categorized as intensive subsistence and primitive subsistence farming.

1. Intensive Subsistence Farming: In this type of farming, the farmer cultivates on a small plot of land. He uses simple tools and more labour. Places which have fertile soils and where the climate allows a large number of days with sunshine are suitable for this type of farming. In favourable climates, farmers are able to grow more than one crop in a year. Rice is the main crop in this type of farming. However, wheat, maize, pulses and oilseeds are also grown. This type of farming is prevalent in densely populated areas of the monsoon regions of south, southeast and east Asia.
2. Primitive Subsistence Farming: Shifting cultivation and nomadic herding come under this type of farming.
   • Shifting Cultivation: In shifting cultivation, a small patch of land is cleared by felling the trees and burning them. Then the ashes are mixed with the soil and seeds are broadcast. After a couple of years, the patch of the land is left fallow and the farmer moves on in search of a new patch of land. Shifting cultivation is practiced in thickly forested areas of Amazon basin, tropical Africa, parts of southeast Asia and Northeast India.
   • Nomadic Herding: In this type of farming, cattle, sheep, goat and camel are reared. The herdsmen move from place to place with their animals in search of new pastures. Nomadic herding is practiced in the semi-arid and arid regions of Sahara, Central Asia and some parts of India (like Rajasthan and Jammu & Kashmir).

Type of Farming:

1. Farming depends upon the geographical conditions, demand of produce, labour and level of technology.
2. Subsistence farming and commercial farming are the two types of farming.

• Subsistence Farming: Subsistence farming is practices to meet the needs of the farmer’s family and needs less technology and labour.
• Intensive Subsistence Agriculture: In this farming, the farmer cultivates a small plot of land using simple tools and more labour. Rice is the main crop. Other crops include wheat, maize, pulses and oil seeds. This type of cultivation produce little to be left over and mainly farmers fullfil only personal needs.

Slow combustion is a form of combustion which consumes time and takes place slowly. Cellular respiration is an example of slow combustion. In respiration, glucose is oxidised and carbon dioxide and energy are released in the process. This is a very similar reaction to combustion. When a hydrocarbon burns, such a natural gas or methane (CH₄), it combines with oxygen, producing CO₂ and water and large amount of energy.

However, the energy released in combustion and respiration are very different.
