Answer 2

Correction in question :-

It should be "you" instead of "ypu".

Answer :-

There are many ways to determine whether an organism is alive or not.

Some easy ways to do so are, checking its breath, heart beat, pulse, etc. But, these ways have some limitations as they can only be used for animals which don't include plants and microbes.

So, a better way to check whether an organism is alive or not, is to check the proper functioning of its metabolic systems.
