All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing . When viewed together, these characteristics serve to define life.
What are the 7 characteristics of a living organism?
There are seven characteristics of living things: movement, breathing or respiration, excretion, growth, sensitivity and reproduction .
What 5 things are necessary for an organism to live?

Why can’t things live forever?
Answer by Paul King. It’s not that living things die; it’s that multicellular organisms die . ...

What is the simplest living organism?
But if we look for the simplest creatures on the planet, we will find a wee bacterium that lives happily in the digestive tracts of cows and goats: Mycoplasma mycoides . It builds itself from a very modest blueprint—only 525 genes. It’s one of the simplest life-forms we’ve ever seen.
Why do living beings need food?
Every organism needs to take food to get energy and to perform life processes . The living organism undergoes many life processes like nutrition, respiration, digestion, transportation, excretion, the circulation of blood, and also the reproduction. ... The energy to the organism is mostly supplied through the food.
