nitrogen
Oxygen, now about 20% of the atmosphere, was not part of the original atmosphere of hthe Earth. It was produced by plants, after life developed.
Yes, nitrogen makes up about 78% of Earth's atmosphere. It is an essential component for living organisms, such as plants, to build proteins and other essential molecules. Nitrogen gas (N2) is a stable molecule that is relatively inert and does not readily react with other substances.
The atmosphere is primarily composed of Nitrogen (N2), which accounts for 78%. Oxygen follows, accounting for 20% of its volume, with argon less than 1%. The remainder is composed of particulates and trace gases, including water vapor.
The atmosphere is made mostly of gas because gases have low molecular densities, allowing them to be easily suspended in the Earth's gravity. The gases in the atmosphere help regulate temperature and provide elements essential for life, such as oxygen.
In the absence of oxygen, nitrogen in the ground is typically found in the form of nitrogen gas (N2). Nitrogen gas makes up about 78% of Earth's atmosphere and can dissolve in soil and groundwater, providing an essential nutrient for plants and microorganisms.
Plants release oxygen gas (O2) into the atmosphere as a byproduct of photosynthesis.
Plants use carbon dioxide (CO2) in the atmosphere during photosynthesis to form sugars and oxygen. This process is essential for the growth and survival of plants.

The answer choices are:Plants take in nitrogen gas from the atmosphere.Bacteria convert nitrogen gas into a form that plants can use.Water absorbs nitrogen.Animals take in nitrogen gas from the atmosphere.
Carbon dioxide is the gas used by plants for the raw material of photosynthesis. But the essential core of photosynthesis is the plants ability to split H2O into H and O. From this it uses the H to help form complex biochemicals. The O is discharged as waste gas. Carbon dioxide is not usually considered a trace gas in the atmosphere, as it represents 0.4% of the air.
carbon dioxide
yes
Oxygen is the gas in the atmosphere that is continually being renewed by plants through the process of photosynthesis. Plants use carbon dioxide and sunlight to produce oxygen as a byproduct, helping to maintain the balance of gases in the atmosphere.
Plants add oxygen to the atmosphere during photosynthesis or food making.
