What are the characteristics of life?

RINGER.

To remember the charactristics of life, scientists use a word "RINGER". If a thing has all the properties mentioned in "RINGER" than the thing is considered as living. Me and my friends made it "NIGERR". In both ways you can remember it.

• Respire
• Irritavity (sensitivity)
• Nutrition (eat food)
• Growth (permanent increase in size)
• Extrete (taking out waste materials or simply "poop and pee")
• Reproduce
