How would the atmosphere change if there were no more plants?

There would be significantly more CO2 in the atmosphere because plants take in CO2 during photosynthesis and fix the carbon into glucose.

We would all dye from not being able to breath.

Animals, including man, add carbon dioxide to the atmosphere by breathing it out, and by decomposing, when dead. Man also adds CO2 to the atmosphere by burning fossil fuels (coal, oil and natural gas), and by destroying forests. If there were no animals, including man, then the trees and other vegetation would grow again, with little to destroy them. Trees would absorb and store carbon, and the levels of carbon dioxide in the atmosphere would…

Ozone in the lower atmosphere is harmful to plants and animals and the biosphere is where plants and animals live, so the more, the worse.

the dead animals are descomposed, and the nutrients now form part of the lithosphere. The animal breathing changes the atmosphere. The animal blood or waste can change the hydrosphere A change in the biosphere, litosphere, atmosphere or hydrosphere can make another change in biosphere A change in atmosphere (more tempereture) can evaporate the water, kill the animals and plants and changes in temperature (heat and cold) can break stones (lithosphere)

The atmosphere of Venus could be thought of as being more friendly to plants than to humans, but such high levels of CO2 trap so much heat that the runaway greenhouse effect would burn any Earth plants to cinders in short order.

Coal fired plants.

More green plants!

Due to photosynthesising, single celled organisms, the atmosphere now has much more oxygen in it. this is possibly the most important change as with out we would exist. The atmosphere originally had much more carbon-dioxide and made the planet so hot humans would not be able to survive.

Yes, but usually slowly. At one time there was no Oxygen in the atmosphere, (and quite a bit of methane) and a little less than a billion years ago there was more than 25 % O2 (age of the giant insects ... with lots of plants on land.)

during photosynthesis, plants use co2 as one of their reactant and produce oxygen. with less plants/trees, more co2 are being trapped within the atmosphere which makes global warming and influences the climate.

Plant more Plants

We are adding more and more carbon dioxide to the atmosphere. This is causing global warming and climate change.

Not exactly but food, like any gas, liquid or solid, is made up of one or more chemicals. Plants growing is 'chemical change'. Food rotting is 'chemical change' Cooking food is 'chemical change'. Without 'chemical change' or chemical reactions, plants would not exist. Human beings would not exist. Anything we eat would not exist. Planet Earth would not exist!

Marine plants contribute far more oxygen to the earths atmosphere than land plants they also use up a lot of CO2 in so doing.

well as it is we produce massive amounts of pollution. about 60% of it is cleared by trees and plants however as more pollution is produced in larger amounts it begins to overwhelm the plats even more. and as cites expand there are killing more trees and parks, so that pollution is grabbing a hold over our planet at a faster rate. hope this helps

Photosynthesis removes carbon dioxide from the atmosphere and stores it in plants and trees. More than half a large tree is carbon. Carbon dioxide in the atmosphere is one of the greenhouse gases causing global warming, so removing it helps combat climate change.

There are more than two gases in the atmosphere. You need to specify the ones you are asking about.

It is the increase in the levels of greenhouse gases, carbon dioxide and methane that are causing more heat to be retained in the atmosphere. This extra heat is global warming, and this is causing climate change.

The heat would make no difference, but the atmosphere would increase the weight.

The atmosphere is one of the most important spheres. If there was no atmosphere there would be no biosphere. If there was no biosphere there would only be the geosphere. Also, without no atmosphere there would be no more hydrosphere because of space radiation. So without the atmosphere there would only be the geosphere.

Earths atmosphere has changed in a few ways. It contains more pollutants and carbon dioxide which is a greenhouse gas.

Photosynthesis is carried on by plants that produce oxygen.This process has replaced all oxygen that is in the atmosphere for more than 2 000 years.

Either more or less materials would be in the atmosphere.

There would be more carbon dioxide (CO2) in the atmosphere. Carbon dioxide is a greenhouse gas, so more heat would be captured in the atmosphere and global warming would increase.

More of the sun's heat trapped in the atmosphere would mean the greenhouse gases would become warmer. The earth and the atmosphere would become hotter, and global warming would speed up.

The full question is: Which of the following describes a possible effect that an increase in carbon dioxide in the atmosphere would have on an ecosystem? A. Animal productivity would increase because more carbon dioxide would be available for cellular respiration. B. Plant productivity would increase because more carbon dioxide would be available for photosynthesis. C. All of the organisms would immediately die because carbon dioxide is poisonous to both plants and animals. D. Plant…

I think it's "PLANTS" :D

CO2 has affected climate change, by thickening the atmosphere - this causes more radiation emitted by the sun to become trapped within the atmosphere, instead of reflecting back into space.

This would mean that there would be more earthquakes, more natural disasters. The polar ice caps would melt in the North and South pole. The average global temperature would go up, also the sea levels would rise due to the melting of the polar ice caps. More CO2 in the atmosphere etc...

The carbon cycle removes carbon from the atmosphere, but only temporarily. Photosynthesis, when plants grow, is the only way to permanently remove carbon from the atmosphere. So we need to plant more forests.

No, there is not less oxygen, if anything there is more because of the lack of pollution and more living plants around it in the ocean and on the island.

There would be no more plants if they were not fertilized. Fertilization is necessary for reproduction.

There is real evidence that there is man made climate change. It is estimated that most of the planet would be covered in water.

Co2 (Carbon dioxide) apparently contributes to the thickening of the atmosphere. The atmosphere thickening means that it retains more heat that can't exit through the atmosphere and therefore heats up the Earth. But don't worry about it too much- climate change is natural.

Trees and plants absorb harmful gases from our atmosphere and convert them into clean Oxygen or O2. If we plant more trees, they can absorb more of the gases us humans are emitting, preventing global warming and climate change.

Carbon dioxide causes heat to be trapped in Earth's atmosphere instead of escaping back into space. If there were more carbon dioxide, then the temperature of Earth would rise. This is what global warming is.

True. it would get a lot more warmer.

more oxygen was consumed

Not much. It's the other way round. Climate change affects the winds. More heat in the atmosphere is more energy, which is making storms and wind more violent.

Heat change and pressure change are the only reasons, but in our atmosphere, more often heat.

The atmosphere prevents the sudden increase in temperature during the daylight hours. And during the night, it slows down the escape of heat into outer space. +++ It would be more accurate and more to the point to state that without the atmosphere there would be no climate!

During spring and summer more plants photosynthesize, removing carbon dioxide from the atmosphere. In fall and winter fewer plants are active, and some even die and decay, which releases carbon dioxide. This is more pronounced in the northern hemisphere which contains the most land mass and therefore the most plant life.

A warming atmosphere causes climate change. This means weather "events" like storms, floods, droughts etc will become more frequent and more severe.

Yes plants use photosynthesis to produce more oxygen, and also oxygen in rocks can escape to the atmosphere.

There are several things that are found in the earth. Some of them include the atmosphere, plants, animals, oceans, mountains and so much more.

No, plants need oxygen for respiration during the dark phase of photosynthesis. They produce more oxygen than they use but, they still need to have oxygen.

The oxygen so characteristic of our atmosphere was almost all produced by plants (cyanobacteria or, more colloquially, blue-green algae). Thus, the present composition of the atmosphere is 79% nitrogen, 20% oxygen, and 1% other gases.

Since Oxygen is a product of Photosynthesis which is what plants do as they take in and use up Carbon di Oxide (CO2) in order to grow. As vegetation was removed there would obviously be a decrease in the amount of Oxygen and an increase of CO2 available in the atmosphere. Therefore we would not be able to breathe. We would be able to breathe but because of the lack of Oxygen we would breathe…

No, it would be more accurate to say they prevent heat from leaving the atmosphere.
