Answer:
Most organisms cannot obtain nitrogen from the atmosphere. Nitrogen fixing bacteria take Nitrogen out of the atmosphere and make it available for consumption by the other organisms, This is important because Nitrogen is an essential building block of life.
It changes the way the earth looks and the resources we are available to
I think that it’s A, D, and F
-the particles do not have a charge
-movement across membrane doesn’t require additional energy
-the particles crossing could be oxygen or water

Answer:
4. The correct pathway for the flow of electron during photosynthesis is mentioned in option D.
> <em>NADP </em>> <em>Calvin cycle.</em>
- Electron is first provided to the photo-system II by the phtolysis of water.
- Then it is passed to photo-system I with the help of plastoquinone (PQ) and cytochrome
. - Finally, electron from the photo-system II is used to reduce NADP to NADPH.
- NADPH and ATP are used in light independent phase or Calvin cycle to synthesize carbohydrate from carbon dioxide.
5. The correct answer is B.) photosynthesis.
- Photosynthesis is the process by which green plants synthesize glucose or carbohydrate from carbon dioxide and water in presence of sunlight and chlorophyll.
- In light independent phase of photosynthesis, it requires ATP and NADPH in order to synthesize food.
- Lastly, oxidation or breaking down of glucose releases energy and photosynthesis is a anabolic process instead of catabolic one.
