The Difference between living and non living

The word ‘living’ can not be defined in a single word or phrases. However, we can distinguish between livings from non living on the basis of following characteristics-

Growth- As time passes living shows growth as number of cells increases and results in increase in mass.

Reproduction- Living organisms produce other living organisms similar in physical characters and traits.

Pollution

Pollution is the introduction of contaminants into a natural environment that causes instability, disorder of brain, harm or discomfort to the ecosystem i.e. physical systems or living organisms. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classified as point source or nonpoint source pollution.
