Then nobody would have any kind of plant life!!!
The Earth's crust is destroyed when subduction occurs.
Earths first life form may be non photosynthetic bacteria.
If earth's moon was destroyed, then we will no longer have normal tide cycles.
Thanks to Physics
Oxygen was the important element missing in Earth's early atmosphere. It was only produced later by photosynthetic organisms.
Depends on what they produce. Phytoplankton are the largest producers of oxygen. Various forms of bacteria and some other life forms are the largest producers of methane. Fish as a whole are likely the largest producers of ammonia. The ocean is a complex biome, be more specific with your question.
Today the Earth's atmosphere is being destroyed by all the pollution by cars and power plants.
Weathering, plate movements and volcanoes destroyed many of the craters
Since there is global warming responsible for ozone depletion. The earth's temperature will increase.
The early Earth's atmosphere lacked oxygen because oxygen was not initially produced by photosynthetic organisms. Instead, the atmosphere consisted primarily of gases emitted from volcanic activity, such as water vapor, carbon dioxide, and nitrogen. Oxygen levels increased over time as photosynthetic bacteria and plants evolved.
we die because of the solar radiation, right now the ozone and the earths magnetism protects us
Marine plants contribute far more oxygen to the earths atmosphere than land plants they also use up a lot of CO2 in so doing.
