Explanation:

For the digestive system, food is broken down to get nutrients and energy, with waste as a by - product. Vehicles need fuel and other inputs to move and transport. The healthcare system uses staff, supplies, and funding to treat patients. Elevators use electricity and control signals to move vertically.

Answer:

Digestive System

• Purpose: Break down food for nutrient absorption and energy - extraction.
• Input(s): Food and water.
• Output(s): Waste (feces), absorbed nutrients.

A Vehicle

• Purpose: Transport people or goods from one place to another.
• Input(s): Fuel (e.g., gasoline, diesel, electricity), air (for combustion - engines), maintenance materials (oil, etc.).
• Output(s): Movement of the vehicle, exhaust gases (for combustion - engines), heat.

Healthcare System

• Purpose: Provide medical care, promote health, and treat diseases.
• Input(s): Medical staff (doctors, nurses, etc.), medical supplies (medicines, equipment), patients, funding.
• Output(s): Treated patients, improved health outcomes, health - related data.

Elevator

• Purpose: Transport people and goods vertically between floors.
• Input(s): Electricity, control signals (from buttons), maintenance materials.
• Output(s): Vertical movement of passengers and cargo.
