Step-by-step explanation:
Energy is the most important ingredient for life. Organisms use energy in diverse ways. Scientifically, energy is defined as the ability to do work. Without this ability, organisms would not exist.
So, the most important process is one that can furnish the body with energy.
- The respiratory system happens to be the one that furnishes the body with energy.
- During respiration, the energy needs of the body is met by series of processes.
- Oxygen is taken in and use to liberate calories from chemical substances packed with energy.
- So, without respiration, the bodily energy demands will not be met.
