If there were no plants, the atmosphere would undergo significant changes. Without photosynthesis, which plants use to convert carbon dioxide into oxygen, levels of carbon dioxide would rise while oxygen levels would decline. This would lead to increased greenhouse gas effects, contributing to climate change, and could result in a less breathable environment for most aerobic organisms. Ultimately, the absence of plants would disrupt ecosystems and diminish biodiversity.
there would be no water for the plants
If nitrogen disappeared from the atmosphere, many organisms would die as they rely on nitrogen to build proteins and DNA. The loss of nitrogen would disrupt ecosystems, affecting plant growth and the animals that depend on them for food. Additionally, the composition of the atmosphere would change, potentially affecting climate and weather patterns.
The Earths surface would be much colder than it is.
The moon does have an atmosphere but it is very thin, it only has one part unlike earth's atmosphere. The atmosphere of the moon is called the Exosphere. Nothing bad will affect it just more craters will be found.
Plants play a crucial role in creating an atmosphere suitable for sustaining life by producing oxygen through photosynthesis. Oxygen is necessary for the respiration of many living organisms, including humans. Additionally, plants help regulate levels of carbon dioxide in the atmosphere, which is important for maintaining a stable climate. Without plants, the atmosphere would lack the necessary oxygen levels to support life as we know it.
what would happen to plants nutrition if plants did not have roots
The excess CO2 in the atmosphere will increase global warming.
If the atmosphere had always been pure oxygen, life as we know it would never have developed. If the atmosphere suddenly became pure oxygen, wild fires would rage throughout the world, and most plants and animals would die in a short time.
The excess CO2 in the atmosphere will increase global warming.
Our moon has no atmosphere to touch.
If there were no plants it is unlikely that there would be any atmosphere at all. Plants remove carbon dioxide (CO2) from the atmosphere and are a vital part of the carbon cycle. No plants would mean huge increases of greenhouse gases in the air and a runaway greenhouse effect. Animals on the other hand would make little or no difference to the levels of carbon in the atmosphere.
Plants are vital for the ecosystem as they produce oxygen through photosynthesis, provide food for animals, and help regulate the climate by absorbing carbon dioxide. Without plants, the food chain would collapse, and the atmosphere would be lacking oxygen, which would lead to a catastrophic imbalance in the ecosystem.
everyone would die
They would die
You get pea plants.
If humans killed ALL plants on earth, we would all suffocate. This is because plants convert co2 (carbon dioxide), which is exhaled by all animals, back into oxygen through photosynthesis. If they didn't convert co2, the earth's oxygen supply would depleat and we would fill the atmosphere with co2, and we would have no oxygen.
Trees and plants take in Carbon Dioxide and in turn breathes out oxygen. If there was no plants and trees we would die. The whole of the world depends on plants and trees. Not meaning to sound like a tree-hugger, but don't cut down trees...plant them!
