They’re both passive processes meaning they don’t need energy to occur, both are spontaneous processes
Biotic and living are the same thing, abiotic would be non-living
It's not alive, nor is it even an organic compound.
- It cannot respond to stimuli (Responsiveness)
- It cannot secrete hormones (Secretion)
- It cannot send messages along a nervous system or anything similar (Conductivity)
- It cannot break down compounds to usable energy forms (Digestion)
- It cannot absorb broken down compounds as an energy source (Absorption)
- It cannot reproduce (Reproduction)
- It cannot grow--it has no cells (Growth)
- It cannot exchange gases between cells (Respiration)
- It cannot rid itself of waste material (Excretion)
