How can you tell if something is living or nonliving? Sometimes it can be a challenge to determine if something is alive.For an organism to be considered alive it must have all of these 7 characteristics.
The organism must be made of cells.
Have the ability to grow and develop.
Have the ability to reproduce and produce offspring.
The living organism must contain DNA.
The organism must use energy for daily activities.
The living object must have the ability to respond to stimuli.
Finally, the organism must have levels of organization.
If an object does not contain one of these traits or abilities, the object is considered nonliving.
In Biology a living object can be described as a biotic factor.
Examples include,
plants
animals
bacteria
fungi
protists
All of the objects are different than nonliving objects because they have all of the characteristics of living objects.
Abiotic factors on the other hand do not have all of the living characteristics and are considered nonliving.
For example, a rock does not use energy nor reproduce.
Common examples of abiotic factors are,
air
water
rocks
sand
ice
sunlight
An object that is not alive is described as an abiotic factor.
