If there was no plant life on earth, there would be no human life, or animal life of any kind. Without plants, there would be no autotrophs (organisms that produce their own food) so other organisms, which need to consume food, there would be no food for other organisms. Also, since plants produce oxygen for heterotrophs (organisms that consume food to produce energy), there would be no oxygen for us to breathe and we would suffocate.
As the first photosynthetic organisms increased in number, the concentration of oxygen in Earth's atmosphere began to increase. Organisms that could respire aerobically would have evolved and thrived. The sun's rays would have converted much of the oxygen into ozone molecules that would then have formed a layer that contained more ozone than the rest of the atmosphere.
Earth would be filled with dead organisms.
Nothing. There are no organisms on Earth that depend on humans for food. There might be some species that would die out naturally without human intervention.
If there were no producers on Earth, such as plants and algae that convert sunlight into energy through photosynthesis, life on Earth would not be sustainable. Producers are at the base of the food chain, providing energy and nutrients to other organisms. Without them, there would be no source of food or energy for consumers, leading to the collapse of ecosystems and the extinction of most organisms.
No, Earth's gravity would not affect Pluto. However, the suns gravity does.
A chemical that harms prokaryotic cells would specifically impact bacteria, which are prokaryotic organisms. It would not affect fungi, plants, or animals, as they are eukaryotic organisms.
Decomposers break down dead or once living organisms. Without decomposers, the earth would be littered with the bodies of dead animals, plants, and other organisms
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.
Another moon would not affect Earth's gravity. The gravity a body exerts is determined by its mass, not by the mass of objects affected by it. This would, however affect other things, chief among them tides, which are controlled by the gravity of the moon.
Only one star has any effect on Earth. The sun is the source of the heat and lightwithout which there would be no life on Earth. None of the other stars has any effect.
