Living things: Things which can grow, move, breathe and reproduce.
Non-Living things: Things which cannot grow, move, breathe and reproduce. They do not have any kind of life in them. Examples of nonliving things are rocks, bucket and water
A non-living thing is anything that was never alive. In order for something to be classified as living, it must grow and develop, use energy, reproduce, be made of cells, respond to its environment, and adapt.
Living things
Living things exist and are alive, sustaining life. They own life. Living things have structures known as cells, they grow and exhibit movement or locomotion. Living things are capable of producing a new life which is of their own kind through the process of reproduction. Examples of living things are: Animals, birds, insects and human beings
Characteristics of living things:
- Living things exhibit locomotory motion, they move. Animals are able to move as they possess specialized locomotory organs, for example – Earthworms move through the soil surface through longitudinal and circular muscles. Plants respond to the movement of the sun.
- Living things respire. Respiration is a chemical reaction which occurs inside cells to release energy from the food. Transport of gases takes place. The food that is ingested through the process of digestion is broken down to release energy that is utilized by the body to produce water and carbon dioxide as by-products.
Non-living things.
Examples of non living things include stone, pen, book, cycle, bottle, etc.
Characteristics Of Non living Things
- Non living things are lifeless. They do not have cells, there is no protoplasm which forms the basis for life to exist.
- They do not have a definite and certain size of their own. They take the shape of the substance they are contained in, for example, a liquid takes the shape of its container. The change in the state of a non living thing is due to an external influence.
