Question

Explain how ventilation provides oxygen for respiration which releases energy for work?

Answer 1

Do you mean if your on a respirator? The type of ventilation you mean is unclear. Ventilation, in itself, doesn't really provide oxygen, it just moves air around.

Since your question is in the living green section, I'm assuming your talking about the air in a building. In a green building air is circulated naturally. Warm air rises, as the air cools it sinks back down, repeating the cycle.

Answer 2

When u breath out is CO2 which is what the plants need to createe food , with sun light. The plant returns O2 to us and keeps the C to creat it's food. It is a cycle of life for most animals.
