1How do plants absorb nitrogen?
2. Name the different variables of atmosphere.
3. What is the importance of carbon di oxide and oxygen for living beings?​

Answer 1

Explanation:

1.Plants absorb nitrogen from the soil as both NH₄⁺ and NO₃⁻ ions, but because nitrification is so pervasive in agricultural soils, most of the nitrogen is taken up as nitrate. Nitrate moves freely toward plant roots as they absorb water.

2.The air in our atmosphere has some variable components to it as well. These variable components include water vapor, dust particles, and ozone. Although these are found in small amounts, they can have significant effects on weather and climate. The amount of water is the atmosphere varies between 1 and 4%.

3.Carbon dioxide (CO2) and oxygen (O2) are the most important gases for living organisms. CO2 is vital for use by plants in photosynthesis, in which plants use CO2 and water to convert the Sun's energy into food energy. This food energy is in the form of the sugar glucose (C6H12O6). Plants also produce O2.

hope this help u mate!!!!

What is the important of carbon dioxide and oxygen for living beings?

What is the important of carbon dioxide and oxygen for living beings?The carbon dioxide and oxygen cycle is critical to life on Earth. Humans, and most other organisms, need oxygen to survive. ... That is why it is so important to help someone who cannot breathe by providing them with oxygen. Plants and other organisms that perform photosynthesis rely on animals for carbon dioxide.
