What depends on the quantities and qualities of these factors to maintain life?
Survival
To maintain a stable internal environment
Homeostasis
Three things that keeps homeostasis maintained

Effectors
Levels of organization
Chemical level, cellular level, tissue level, organ level, system level
Atoms join to form molecules which combine to make organelles
Chemical level
Basic structural and functional unit of life
Cellular levels
Groups of cells having a common origin become specialized for certain functions
Differentiation
Cells are organized into tissue
Tissue level
Tissues are organized into organs
Organ level
Organs are organized into systems and they make up an organism
System level
One cell has to do all the functions and is more complex cell to cell, that one cell is more complex than we are
