LIVING AND NON-LIVING THINGS QUIZ

Custom Search

You answered that salt is non-living but was once part of a living thing or that water is non-living and was never part of a living thing.

Well done, you are correct!

It is impossible to know the origin of the salt in the question. Some of it may well once have been part of a living thing. When living organisms die their bodies are decomposed and the minerals are recycled. Some of the salt, however, may have its origins in the weathering of rocks.

Now try question 14
