Introduction About Living And Non Living Thing :
Living things usually grow during their life cycle. Many living things move on their own although some, like plants, do not. Living things need food, water, and a place to live. Almost all need air, but not all. Examples of living things are plants, animals etc. and non living things are chair, car, etc.
Difference Between Living And Non Living Thing :
Living things are sensitive to their environment. Non-living objects are not. Living things also respond to internal changes. For example, you quickly pull your hand away from a hot iron because of an impulse or feeling. Living things are able to reproduce. People, snakes, insects, fish, or any other organisms have young which in time develop into adults. Trees produce seeds which will grow into an adult tree. Non-living things do not have this ability.
FEATURES OF LIVING THINGS :
Living things move, have senses, feed, respire, excrete, reproduce, grow.
Energy For Living Thing :
Nutrition means using matter and energy. All living things need matter to grow and to repair their body and energy for movement and work. Nutrition is the way living things take and use food. Animals, for example, need to digest food (digestion) in order to obtain nutrients. When nutrients combine with oxygen in the cells, it produces energy (this is respiration). This process also produces wastes. When we breathe out, we produce waste products (water and carbon dioxide). Some waste is poison and we must remove it by excretion. Plants do not get their energy from food. They make their food by photosynthesis. This means that they catch energy from sunlight and they trap this energy in food (sugar). To take energy from food, plants respire, so they combine sugar with oxygen and this process produces wastes: carbon dioxide, and water vapor.
Interaction means responding or reacting to changes in the surroundings. For example, when we are hot, we sweat and when we are cold we shiver. These are body responses to the temperature changes. Plants also respond by moving towards or away from the sunlight (phototropism). Reproduction is the way living things make more of themselves. It allows each kind of living thing to exist on Earth for a period of time.
In the meantime non-living things are the exact opposite of living things. They do not exhibit any growth and they do not have a life of its own. They do not eat, sleep, reproduce, and respond to any forms of stimuli. There are non-living things however that can grow in size. An example would be icicles formed from rain and snow. They grow in size however they are not living.
