Can't, it's a false statement. Live existed for > billion years before photosynthesis.
1)The tree respirates in the absence of light 2)the photosynthesis which is the base for life on earth
without photosynthesis there would be no life on earth... therefor you would not exist.
The process that makes life possible on Earth is photosynthesis. This is the process by which plants and other organisms convert sunlight into energy, releasing oxygen as a byproduct. Oxygen is essential for the survival of most living organisms on Earth.
If there were no light on Earth, green plants would be unable to perform photosynthesis, the process through which they convert light energy into chemical energy. Without photosynthesis, plants would be unable to produce the glucose they need for growth and energy, leading to their eventual death. Additionally, the absence of plants would disrupt ecosystems and food chains, as they are primary producers that support herbivores and, subsequently, carnivores. Ultimately, this would result in a significant collapse of life on Earth.
Oxygen is the main component of carbon dioxide, which plants use in photosynthesis. Oxygen is a by-product of photosynthesis. Oxygen is the element that makes most life, plant and animal, possible on Earth. So, photosynthesis not only helps life to flourish. For most organisms, it makes life possible.
If electromagnetic waves did not reach Earth from the Sun, the planet would be devoid of light and warmth. This absence of sunlight would prevent photosynthesis, disrupt the planet's climate balance, and likely render most life forms unable to survive.
If the sun didn't shine, Earth would quickly become cold and dark, making it difficult for life to survive. Plants would die due to lack of photosynthesis, which would disrupt the entire food chain. The absence of sunlight would also affect weather patterns and global climate.
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.
Without radiation, Earth would not receive any energy from the sun, leading to a lack of heat and light. This would result in extremely cold temperatures and darkness, making it impossible for life to exist as we know it. Radiation also plays a crucial role in natural processes such as photosynthesis and the Earth's magnetic field, so the absence of radiation would have far-reaching consequences on the planet.
Life is very possible on earth, if it were not, then we would not exist.
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.
No, photosynthesis is a fundamental process in plant biology where plants use sunlight to convert carbon dioxide and water into glucose and oxygen. Without photosynthesis, plants would not be able to produce energy and oxygen, which is essential for the survival of many organisms on Earth.
