Why do people move through hierarchy from bottom to the top

Answers

Answer:

The lowest levels of the pyramid are made up of the most basic needs, while the most complex needs are at the top of the pyramid. ... Once these lower-level needs have been met, people can move on to the next level of needs, which are for safety and security.

Explanation:

People generally move through the hierarchy from the bottom to the top in order to sustain themselves with the pace of alteration in climatic and other factors.

What is Hierarchy?

Hierarchy may be defined as the process of arranging items, members, organisms, etc. with respect to their characteristics, mode of nutrition, energy derivation, etc. By this, people are subdivided into numerous classifications from the bottom to the top.

The lower level of each and every pyramid represents the fundamental requirements of the people while complicated needs are illustrated at the top.

Once the requirements of lower levels are met by the people, they can simply be migrated on to the next level of requirements in order to sustain and achieve their stability.

Therefore, people generally move through the hierarchy from the bottom to the top in order to sustain themselves with the pace of alteration in climatic and other factors.
