What is a relationship between plants and humans?
-Humans benefit from plants because plants being producers are able to produce their own food and therefore, supply people with food. -Through a process called photosynthesis, plants give out oxygen while absorbing carbon dioxide. -This reduces the levels of carbon dioxide in the atmosphere as well as increases the oxygen content in the atmosphere.
What are natural resources of CO2?
Natural sources of CO2 include volcanic eruptions, respiration by plants and animals, and decomposition of organic matter. Human activities, such as burning fossil fuels and deforestation, have significantly increased CO2 levels in the atmosphere.
What is the most likely effect a decrease of plant life in the biosphere would have on the atmosphere?
As a byproduct of photosynthesis, plants produce oxygen. A decrease in plants would mean a decrease in the amount of oxygen being released into the atmosphere, although such a decrease would have to be large in order to produce a noticeable effect.
How do plants help sequester carbon through photosynthesis and contribute to reducing the levels of greenhouse gases in the atmosphere?
Plants absorb carbon dioxide from the air during photosynthesis, using it to make food and grow. This process helps remove carbon from the atmosphere, reducing the levels of greenhouse gases that contribute to global warming.
Which plants benefit humans?
Almost all plants benefit humans

What would happen to the atmosphere if no plants?
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.
Why earths atmosphere today contains more oxygen than earth atmosphere?
The increased oxygen levels in Earth's atmosphere today compared to earlier in its history are due to the evolution and proliferation of photosynthetic organisms like plants and cyanobacteria. These organisms release oxygen as a byproduct of photosynthesis, gradually increasing its concentration in the atmosphere over millions of years.
How might increased carbon dioxide in the atmosphere benefit plants?
Increased carbon dioxide (CO2) in the atmosphere may increase the growth and yield of some plants. However, there may be drawbacks. A 2012 study has shown that wheat production (the world's most important crop) will rise through global warming, if there is enough rain, but the wheat holds less nourishment than before.The study included 43 field experiments with 17 different varieties of wheat, carried out in ten countries across four continents. They all showed the same result.See the link below.
Why do carbon dioxide levels change seasonally?
Carbon dioxide levels change seasonally due to the natural processes of photosynthesis and respiration in plants. During the spring and summer months, plants take in carbon dioxide for photosynthesis, which reduces the levels in the atmosphere. In the fall and winter, when plants go dormant or lose their leaves, respiration releases carbon dioxide back into the atmosphere, causing an increase in levels.
How did the oxygen in your atmosphere get there?
The way the oxygen got into our atmosphere is when the green plants do photosynthesis. Green plants take in carbon dioxide, sunlight, and water to make glucose and of course oxygen. After a while, the plants did enough photosynthesis that the earth got an atmosphere .
Why was there no oxygen in earths original atmosphere?
The early Earth's atmosphere lacked oxygen because oxygen was not initially produced by photosynthetic organisms. Instead, the atmosphere consisted primarily of gases emitted from volcanic activity, such as water vapor, carbon dioxide, and nitrogen. Oxygen levels increased over time as photosynthetic bacteria and plants evolved.
How the boisphere affect the atmosphere?
The biosphere affects the atmosphere through processes like photosynthesis, where plants take in carbon dioxide and release oxygen. This helps regulate the levels of greenhouse gases in the atmosphere. Additionally, activities like deforestation can lead to increased levels of carbon dioxide in the atmosphere, contributing to climate change.
What are natural resources of CO2?
Natural sources of CO2 include volcanic eruptions, respiration by plants and animals, and decomposition of organic matter. Human activities, such as burning fossil fuels and deforestation, have significantly increased CO2 levels in the atmosphere.
Explain the relationship between plants and an atmosphere suitable for sustaining life?
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.
How did the evolution of plants change the earth's atmosphere?
The evolution of plants, particularly the development of photosynthesis, significantly increased oxygen levels in Earth's atmosphere. Plants, along with other photosynthetic organisms, converted carbon dioxide into oxygen as a byproduct, leading to the oxygen-rich atmosphere we have today. This shift was instrumental in creating conditions conducive to supporting diverse forms of life.
The oxygen content in the atmosphere of the early Earth is thought to have increased significantly once which of these developed?
green plants / algae
