Q.11953·Miscellaneous·2014·EasyEven in the most primitive societies the great majority of people satisfy a large part of their material needs by exchanging goods and services.

Q.11954·Miscellaneous·2014·EasySoil scientists have shown that the soil teems with millions of living things, many of them useful, others harmful.

Bacteria, which are microscopic living things break down dead plants and animals and make humus, or take nitrogen from the air and change it into substances that plants use. The living things that do harm include other bacteria and fungi which cause diseases. Other harmful things are pests such as wire worms which feed on the roots of grass and other plants.
