Answer:
ollowing are the important 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.
Living things are sensitive to touch (and other stimuli as well) and have the capability to sense changes in their environment.
They grow. Living things mature and grow through different stages of development.
One of the striking features is that living things are capable of producing offsprings of their own kind through the process of reproduction, wherein genetic information is passed from the parents to the offsprings.
They acquire and fulfil their nutritional requirements to survive through the process of nutrition and digestion, which involves engulfing and digesting the food. Some living organisms are also autotrophic, which means they can harness the sun’s energy to make their food.
The digested food is eliminated from the body through the process of excretion.
The important characteristics of non-living things are mentioned below:
Non-living things are lifeless. They do not have cells, and there is no protoplasm which forms the basis for life to exist.
Lack of protoplasm leads means no metabolic activities.
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. Stones, rocks and boulders are moulded by the changing environment and landscape. The change in the state of a non-living thing is due to an external influence.
Non-living things “grow” by accretion. It occurs through adding materials externally. For example, A snowball may increase in size due to the accumulation of smaller units of its own to its outer surface.
Non-living things never die as they do not have cells with a definite lifespan. Immortality is a distinguishing factor.
Fundamental life processes such as reproduction, nutrition, excretion, etc. are absent in non-living things
