The Ecosystem would shut down, and eventually the planet would become unlivable
No. Even then, anything that could wipe out microorganisms on earth would wipe out all other life as well.
In my knowledge, the microorganisms lived first on earth.
Although bacteria and other microorganisms are essential to many of the processes of life on Earth, they have adverse effects in some regards. Some create disease among plants and animals, and others generate methane gas (classified as a natural pollutant) in their decomposing reactions.
Hardly any - they are very far away. However, a supernova (which would come before a neutron star) could have catastrophic effects on Earth, if it were to happen in our neighborhood (up to a few thousand light years!).

If there were no microorganisms on earth, nothing else would be living, either.
microorganisms lived on earth 3.5 billion years ago.
then plants will die and oxygen will be eliminated from earth and life as we know it will be over
The earth's constant orbit around the sun is caused by an equilibrium between two forces - the gravitational pull of the sun, and the earth's velocity acting at a right angle to it. If that gravitational pull was suddenly eliminated, the earth would continue onwards in a straight line.
No. Even then, anything that could wipe out microorganisms on earth would wipe out all other life as well.
Microorganisms are found in just about every conceivable environment on Earth.
people will die
In my knowledge, the microorganisms lived first on earth.
Microorganisms are the basis of many processes that sustain life. If all the microorganisms on earth were to suddenly disappear, then the nitrogen cycle would be immediately disrupted, as nitrification would no longer occur. Many oxygen generating bacteria would be gone. The human body itself contains many symbiotic microorganisms, although the actual effect their disappearance might cause is unclear.
earth eliminated
waste created by cellular metabolism is eliminated by the nephridia.
No, it only effects parts of earth. Earthquakes don't affect the whole solar system. That's why they call them earthquakes. Because they happen on the earth and the earth only.
