yes
Salt can kill almost anything if there is too much so yea it can.
Without gravity in our solar sytem and our universe everthing would float and it would affect our orbit in the solar system
it doesn't because solar energy is a renewable resource
I guess that if light of shorter wavelength (red) it would have a higher energy which would mean that it would have more photons per joule.
You wouldn't have any power in your home,calculator,etc.

Yes solar energy is the CAUSE of our seasons.
Solar storms can potentially affect solar panels by disrupting the performance of the electrical components or causing damage to the panels themselves. However, most modern solar panel systems are designed with protective measures to minimize the impact of solar storms.
The strength of the planet's gravitational field and exposure to solar wind.
Trees use solar energy for photosynthesis, removing carbon dioxide from the atmosphere and using the carbon to grow. They don't affect solar energy in any way.
Most light-bulb's would provide very little energy to a solar cell. Solar cells use a bandwidth that is not the main portion of a incandescent light bulbs output.
That is highly unlikely. Earth's magnetic field prevents the effects of solar flares from coming close to the surface in all but the most severe instances.
