What features help us identify living organisms?

Living organisms can be identified by characteristics such as growth, respiration, reproduction, response to surroundings, excretion, and adaptation. These features separate living things from non-living things.

All living organisms perform basic life processes that help them survive. Plants and animals need energy, exchange gases through respiration, remove waste materials, and respond to changes in their environment. Many organisms also reproduce to continue their species.

Living beings may differ greatly in their size, shape, habitat, and behaviour, but they share these common characteristics. Understanding these features helps in recognizing life forms, comparing organisms, and studying the diversity present in the living world.
