(a) Characteristics of Living Organisms
Living organisms share the following characteristics:
1 - Movement 2 - Respiration
An action by an organism or part Chemical reactions that break
of an organism that causes a down nutrient molecules in
change in position or place living cells to release energy
3 - Sensitivity 4 - Homeostasis
Ability to detect stimuli in The ability to control
their surroundings and to their internal conditions.
