Characteristics of Living things

Everything around us is either living or nonliving things. Living things are things that are alive. Nonliving things are things that were not alive or have never been alive. But sometimes it is not easy to tell whether something is alive or not. A dog palying with its tail is certainly a living thing. A duck flying in the air is also a living thing. But how about plants? We show that they are just keep quiet in their places without moving everywhere. Can we say plants as the living things too?

To be able to categorize as a living thing, an object should show 7 characteristics of living things which are:

1. Living things grow

2. Living things obtain and use energy by feeding food.

3. Living things move.

4. Living things reproduce.

5. Living things respond to their environment.

6. Living things give off waste (excrete)

7. Living things breathe.

Sometimes nonliving things also show some of the characteristics of living things. Look at the stalagtit or stalagmit. They grow. So, are they living thing because they grow? Or look at a car. It can move. But because a car can move, do we categorize it as a living thing? To be able to categorize as living things, an object must show all 7 characteristics of living things.
