Living and Non-Living Things
We see many things around us. These things can be categorized into two groups living things and non-living things.
Plants, human beings and animals are living things.
Living thing displays the following characteristics:
Living things can move
Living things show movement by moving parts of their body. For example, a horse runs from one place to another, birds fly, and fishes swim. Plants do not move from one place to other but show movement by moving their part. For example, leaves bend towards the direction of sunlight.
Living things grow
Living things grow and develop. Human beings are born and grow into adults. Seeds grow into the young plant and then into an adult tree.
Living things breathe
All living things breathe. Different animals have different organs that they use for breathing. Some animals like horse, monkey, dog use their nose. Fishes have gills for breathing. We humans breathe through our nose while plants breathe through small opening on their leaves called stomata.
Living things reproduce
Living things produce new organisms. Some give birth to their young ones while some lay eggs. Plants have seeds and these seeds turn into new plants. Chicken lay eggs and a chick hatch from these eggs.
Living things need food and water
Living things need food to survive and stay healthy. A horse feeds on the grass to obtain energy. A plant makes its own food by the process of photosynthesis. Some animals like lion, tiger, eagle feed on other animals.
Living things feel
Living things have senses. They react to the changes in their surroundings. For example, you remove your hand from the hot pan. The leaves of the mimosa plant close immediately when you touch them. An animal sees, smells, tastes, hears and feels.
Living things die
All living things grow old and die.
We can say something is alive if it displays all of the above characteristics.
Things that cannot breathe, cannot feel, cannot grow, cannot move, and do not give birth to young ones are called non-living things.
For example, table fan, home, car, stone, and many more.
Non-living things are of two types natural non-living things and man-made non-living things
Natural non-living things include rocks, mountains, stars, sun, moon, etc.
Man-made non-living things include umbrella, table, chair, pencil, bottle, etc. These are present in our environment naturally.
