**The Features of Living Things**
Living things are characterized by several distinct features that set them apart from nonliving things. The first feature of living things is their ability to breathe, also known as respiration. This process allows them to take in oxygen and release carbon dioxide. For example, humans have lungs and a diaphragm that help us breathe air through our nose and mouth. Similarly, animals like birds and fish have gills or other breathing organs that enable them to extract oxygen from water.
In addition to breathing, living things also need food and water to survive. Food provides energy for them to perform various functions, such as movement, growth, and reproduction. Human beings eat vegetables, fruits, eggs, and dairy products, while animals like cows and buffaloes eat grasses and plants. Most birds, on the other hand, consume small insects and grains.
However, not all living things produce their own food. Plants are the only living organisms that can prepare their own food through photosynthesis. They use sunlight, water, and soil to synthesize glucose from carbon dioxide. This process occurs in specialized organs called chloroplasts, which are present in plant cells. The products of photosynthesis provide plants with energy, which they use to grow, reproduce, and sustain life.
Living things also possess the ability to feel and respond to their surroundings. They can detect changes in temperature, light, sound, touch, taste, and smell, which enables them to react accordingly. For instance, when we experience pain or joy, our brain sends signals to various parts of the body, triggering a response. Similarly, animals like dogs and birds also respond to stimuli around them, such as barking at strangers or flying away from danger.
Another distinctive feature of living things is their ability to move on their own. Most animals, including humans, walk or run using their legs. Birds, however, use their wings to fly, while fish swim through the water with their tails and fins. Plants also exhibit movement, although it's not as pronounced as in animals and humans. For example, the leaves of a Morning Glory plant unfold every morning and close at night, much like the opening and closing of curtains. Some plants, like the touch-me-not plant, fold its leaves shut as soon as they are touched.
Lastly, living things give birth to young ones, which is an essential feature that distinguishes them from nonliving things. Human beings produce babies after a gestation period, while cows give birth to calves, and birds lay eggs that hatch into baby birds. Seeds also grow into new plants, which eventually produce seeds of their own. These young organisms will continue the life cycle of the species, ensuring its survival.
**The Features of Nonliving Things**
On the other hand, nonliving things do not possess these characteristics. All man-made objects, such as pencils, pens, chairs, and books, are considered nonliving things. They cannot grow, reproduce, or respond to their surroundings in any way. For example, a pencil does not have the ability to move on its own; it remains stationary until someone picks it up.
Additionally, nonliving things do not breathe. Pencils, for instance, do not require oxygen to function; they simply sit there waiting to be used by humans. Similarly, books and chairs do not need air to exist; they can remain static without any external influence.
Nonliving things also lack the sense of touch. A chair does not feel pain or pleasure when someone sits on it or touches its surface; it is merely an inanimate object. The same applies to a book; it does not have the capacity to perceive the world around it through senses like sight, sound, or smell.
In conclusion, living things exhibit several key characteristics that set them apart from nonliving objects. These features include breathing, eating, growing, feeling, and reproducing. Nonliving things, on the other hand, lack these capabilities and are simply inanimate objects that do not respond to their environment.
