Answer 2

Answer:

Any visible movement such as walking, breathing, or growing is generally used to decide whether something is alive or not. However, a living organism can also have movements, which are not visible to the naked eye.  Therefore, the presence of life processes is a fundamental criterion that can be used to decide whether something is alive or not.

Explanation:

For example we humas and some animals are fast moving compared to plants that are generally slow.

But there are evidence that we can assure that someythind is alive like  the following below:

Death

So we can checked if something is alive through there movement whethere it is fast or slow.
