Why is there a pyramid?
The triangle represents Maslows hierarchy of needs that needs to organised into different levels and we must have each level of needs met until we can progress onto a higher level needs, moving towards self actualisation.
Pyramid shows that basic needs must be met before intrinsic ones
Th show that basic needs must first be met before moving on to needs on the next level
The pyramid shows the order of importance of need starting with our base needs and working up to self realisation.
The Pyramid is there because it symbolizes Maslow's Hierarchy of needs.
There are more lower level needs to be met in order to reach the top.
