there will not be water tides
No food for plants=No plants=No food for animals=..................Do I have to say it?........
Yes, the water cycle is essential for human and plant life on earth. Without the water cycle there would be no rain, no rivers, no water to drink or to irrigate crops. Life would be very different.
Seasons. If the axis of the Earth's rotation wasn't tilted with respect to the ecliptic, there would be no "winter" or "summer". There's evidence to suggest that without our seasons, life on Earth would be PROFOUNDLY different.
Without the Sun, there would be no life on Earth.
Your weight on Earth would not be affected.However, your LIFE on Earth would be negatively impacted, as a more massive Sun would burn brighter and MUCH hotter. Life on Earth would probably cease in short order.
There would be no life on Earth
Yes, life would be possible on an Earth with a different tilt to its axis, as long as the different was not massive. For example, if the axis of rotation was parallel to the orbital plane, conditions would be very different and life, if it developed would also likely be very different than life as we now know it.
The orbiting of the earth and the yearly cycle that comes with it are simply part of life. It's no big deal, in the sense that we didn't make it happen and we don't sustain it. The serious issue will arise if the earth ever STOPSorbiting for any reason...
it would be winter and you would have to wear a jaket
The earth would be flat, and probably devoid of life.

No oxygen will be produced. So life will be anaerobic
Earth is the only place known to harbor life. However, scientists have estimated that there are between 100 and 400 billion planets in the galaxy orbiting other stars. Some of these could potentially harbor life, but it would be difficult to find evidence of life since we can never go to them. Some scientists suspect life might exist beneath the surfaces of Europa and Enceladus, icy moons orbiting Jupiter and Saturn and that life may have once existed on Mars, but again there is no direct evidence.
Life on Earth has evolved to cope with the environment of earth. If the gravity were different it is very likely that life would look very different. It is likely that if the gravity differed by a large amount then life would not have evolved at all. Too heavy and Earth would have enormous amounts of hydrogen and would be a small gas giant. Too little and the earth could not keep hold of much of its atmosphere. As a result we would have far less CO2 and the surface would be much colder. Also we would loose our precious ozone layer and the surface would be bathed in solar radiation.
Please be careful on what you are asking. Is the moon really orbiting the earth? or is the sun orbiting the moon? does a cow go meow? or can a dog go moo? what is the meaning of life? what is the circle of life?
No, it doesn't help the Earth. It only protects all the DNA-based life on its surface and in the air above it. The planet itself is not helped by whether or not life is present. If there was no life on Earth, it would be very different. Would the Earth be better off with no life? I don't think so!
One - one side of Earth would be in constant daylight, while the other side would be in constant darkness. Two - life as we know it, would not exist.
