Why would life be impossibleon earth in the absence of photosynthesis?

Photosynthesis is the root source of all foods on Earth. Amongst all organisms inhabiting Earth, plants are the only ones which are able to produce their own foods through photosynthesis.
Without photosynthesis, plants would die as they can't produce foods for themselves. When plants die, animals that eat plants will also die as they lose their food source. Subsequently, other animals which eat these plant-eating animals will also die as they, too, lose their food source. Eventually, every organism will die from starvation.

Do plants photosynthesize or cellular respirate?
This is kind of a guess, but I would say photosynthesis since some of the first organisms on earth were bacteria that did photosynthesis.
What chemical reaction is essential to all life on earth?
Photosynthesis would be one, and respiratory chemistry would be another. But you could also consider the electro-chemical nature of the nerve synapses.
What would happen to life on earth if the sunlight were blocked from the earth surface?
Photosynthesis stops. If it stops long enough, the plant dies.
Why do the process of photosynthesis is so important to people and to all life on earth?
it is the biggest source of energy
Why is photosynthesis viewed to be the most important chemical process on earth?
Because without it we would all die. All the food we eat is either plant or animal. Plants rely on photosynthesis to grow, and animals eat the plants that rely on photosynthesis. Take it away and there's no more food.
Would life on earth would be possible in the absence of photosynthesis?
Can't, it's a false statement. Live existed for > billion years before photosynthesis.
Why do you need photosynthesis?
without photosynthesis there would be no life on earth... therefor you would not exist.
What would happen if plants disappeared from Earth?
If plants disappeared from earth, all life on earth depending on photosynthesis would disappear.
What would happen if earth didn't have gravity?
If the earth had no gravity it follows that gravity would be absent from any mass. In the absence of gravity life would not exist.
If CO2 was not on earth what will earth be like?
If there was no Carbon Dioxide on Earth it would be very different then what it is now. Firstly plants need CO2 for photosynthesis, without CO2 plants could not complete photosynthesis and would die of starvation (photosynthesis is a plants way of making food). Secondly CO2 is a gas that keeps the Earth's temperature at the correct level, without CO2 the Earth would be much colder and therefor unable to support life.
Would there be less oxygen in the air if photosynthesis stopped happening on earth?
yes
Does oxygen continue to be released if carbon dioxide is not available?
It depends on what you mean by "Continue to be released" Photosynthesis cannot function withot carbon dioxide, so in its absence all plant life would die. However, the earth would receive very smal, amounts of oxygen from meteortes, etc.
Do plants photosynthesize or cellular respirate?
This is kind of a guess, but I would say photosynthesis since some of the first organisms on earth were bacteria that did photosynthesis.
Is photosynthesis life or earth science?
i would say its life because its the life of a plant
What chemical reaction is essential to all life on earth?

How is photosynthesis important to earth?
Plants use photosynthesis to make oxygen and glucose. Without plants, all animals including humans would die from no food and no oxygen to breathe.
What happen if photosynthesis stopped happening on earth?
The plants that use photosynthesis would die because the plants would not create food. They would die of hunger. Without another source of food, most of the animals would likewise die off. Most life would die anyway because the oxygen released by the plants would no longer enter the atmosphere to be used in respiration. Photosynthesis is an irreplaceable part of the carbon cycle, on which the vast majority of life on Earth depends.
