There would be no air or oxygen for us to survive.
The atmosphere is one of the most important spheres. If there was no atmosphere there would be no biosphere. If there was no biosphere there would only be the geosphere. Also, without no atmosphere there would be no more hydrosphere because of space radiation. So without the atmosphere there would only be the geosphere.
In the absence of an atmosphere, both the hydrosphere and biosphere would be highly compromised. Without an atmosphere to regulate temperature, protect against harmful radiation, and provide gases essential for life, water bodies would evaporate or freeze, and most life forms would struggle to survive due to lack of oxygen and protection from space-related hazards.
The broadest level of organization that includes all life on Earth is the biosphere. The biosphere encompasses all the ecosystems and living organisms on Earth, interacting with each other and with their physical environment.
Well, considering Earth is a living organism there would be no earth so there is really no point the question your asking. Plus it doesn't much matter because we'd all be dead. So we wouldn't even know that there were no living organisms left on the Earth, we'd be dead.
Ozone in the lower atmosphere is harmful to plants and animals and the biosphere is where plants and animals live, so the more, the worse.
Now that would be biosphere...
Without the biosphere, Earth would likely resemble a barren, lifeless planet with no greenery, animals, or bacteria. Without the atmosphere, Earth would be exposed to harmful solar radiation and extreme temperature fluctuations, making it uninhabitable for most life forms.
The biosphere is all around you. It is the part of the earth and atmosphere that contains life. It goes from the depths of the ocean to thousands of meters high in the atmosphere.
Our moon has no atmosphere to touch.
everyone would die
The atmosphere should have the greatest impact on the other Earth spheres if the atmosphere were catastrophically damaged. If the atmosphere turned poisonous or something, most living organisms will die. So, this damaged air will affect the biosphere. So, with the biosphere damaged from the atmosphere, it will affect the lithosphere. The affected lithosphere would obviously ruin the rocks and minerals on the Earth. With both lithosphere and atmosphere damaged, the hydrosphere would become damaged also because of the poisonous air and a non-healthy Earth.
Not necessarily. The presence of oxygen in Earth's atmosphere is the result of biological processes that have occurred over billions of years, not simply a function of the biosphere's age. Other factors such as the balance of oxygen-producing and oxygen-consuming organisms also play a role in determining atmospheric oxygen levels.
