What was the importance of photosynthesis in the evolution of the earths atmosphere?
Photosynthesis played a crucial role in the evolution of Earth's atmosphere by producing oxygen as a byproduct. This process greatly increased the amount of oxygen in the atmosphere, making it possible for aerobic organisms to thrive and leading to the development of more complex life forms. The rise of photosynthetic organisms also contributed to the stabilization of Earth's climate over time.
Does photosynthesis deposit energy in earths saving account for living organisms?
Yes, photosynthesis is the process by which plants convert sunlight into chemical energy in the form of glucose. This energy is stored in plant tissues and is used by other organisms when they consume plants, making photosynthesis a key component in the energy flow of ecosystems.
How much of earth's atmosphere is composed of nitrogen gas?
The earths atmosphere is made up of 78% nitrogen and 21% oxygen
List 4 major reservoirs for carbon in the earth system?
The atmosphere, the ocean, and the terrestrial biosphere.Carbon can be found in the earths oceanic and continental crust in different types of stones as well as in the soil from the decay of organic matter.
How did earths atmosphere get its free oxygen?
Releasing oxygen into the atmosphereA number of billions of years ago there was no oxygen in the atmosphere. In fact oxygen was a poison to everything that lived. At some point in this distant past, a bacteria managed to absorb a smaller cell that used chlorophyll to photosynthesise. This became a symbiosis relationship where the bacteria protected the little cell, while the little cell fed the bacteria. This successful harmony resulted in a large number of photosynthesising cells that take water (H2O - dihydrogen oxide) and used sunlight as the power source to extract the hydrogen for food and release the oxygen. The released oxygen found it's way into the atmosphere. This is the exact chemical reaction that continues today in all plants and algae.Ok, for those on Study Island the answer is the free oxygen bubbled up from the oceans.
What was the earths atmosphere before photosynthesis?
Without life because when plants do photosynthesis, they produce oxygen.
Earths atmosphere was first changed by?
photosynthesis
What effect does photosynthesis have on the amount of oxygen in the atmosphere?
Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.
What gas was not found in earths early atmosphere but was produced by photosynthesis?
Carbon dioxide
How does the light reaction of photosynthesis affect the earths supply of oxygen?
Photosynthesis is the source of virtually all the free oxygen in the earth's atmosphere.
What was Earths atmosphere before photosynthesis?
It was like a cow in water, and a dove giving birth...
How does oxygen get into earths atmosphere?
The process is very well-known in Biology called the Photosynthesis. It plays an role in plants because plants get it energy from sun.
What component of Earths atmosphere exists entirely as a result of photosynthesis?
Oxygen is the component of Earth's atmosphere that exists entirely as a result of photosynthesis. Plants and other photosynthetic organisms convert carbon dioxide into oxygen during the process of photosynthesis.
What component of the earths atmosphere exists as a result of photosynthesis?
Oxygen is the component of the Earth's atmosphere that exists as a result of photosynthesis. During photosynthesis, plants and other photosynthetic organisms release oxygen as a byproduct. This process helps to replenish and maintain the oxygen levels in the atmosphere, supporting aerobic life forms.
Why is earths composition of earths atmosphere important?
The Chemical Composition of the Earth's atmosphere is important because it holds the Earth together.
How was oxygen added to the earths atmosphere?
Oxygen was added to Earth's atmosphere through the process of photosynthesis by early photosynthetic organisms like cyanobacteria. These organisms released oxygen as a byproduct, which accumulated over millions of years and eventually led to the oxygen-rich atmosphere we have today.
What process adds oxygen to earths atmosphere?
Photosynthesis
