To explain: The importance of developed nations, developing nations, subsistence agriculture and infant mortality rate.

Explanation of Solution

The importance of the given terms is explained below:

1. Developed nations: The countries which have a high living standard and have made themselves independent economically are developed nations. These nations have an economy based more on industry than agriculture. Developed nations can help other nations by providing them aid in various forms at times of need.

2. Developing nations: The countries in which industries have not developed fully and have low living standards in comparison to developed nations are developing nations. Developing nations contribute to the growth of the world economy. Many times the per capita GDP of developing nations is better than developed nations.

3. Subsistence agriculture: Farming to fulfil the needs of their own family only is subsistence agriculture. In this kind of agriculture, the family grows that many crops only which can fulfil the needs of the family, no crops are available for sale or export. Even crops are not available to feed the industrial workforce, this kind of farming is done by families in developing nations.

4. Infant mortality rate: This is the rate by which infants die in the first year of life only. This rate is found to be higher in developing nations and is a measure of the health facilities available in a nation.
