What Happened If Oxygen should be blocked for 5 seconds only

If oxygen were to suddenly stop existing on Earth, the consequences would be catastrophic and far-reaching. Within minutes, all aerobic life forms, including humans, animals, and plants, would begin to suffocate and perish. The absence of oxygen would halt cellular respiration, causing energy production to cease, and leading to rapid organ failure. Ecosystems would collapse, and the food chain would be severely disrupted. The planet would become a barren, lifeless rock, devoid of the vibrant diversity that oxygen sustains. The very fabric of life as we know it would unravel, leaving behind a desolate, oxygen-free environment inhospitable to any form of life.
