Answer 2

The most important criteria to decide that something is alive is the movement. All living things move by themselves without any external help. In some cases the movements of living things are quite fast which can be easily observed but in other cases the movements are very slow and hence observed with difficulty. For example - the movements in most of the animals are fast but the movements in plants are usually slow.
