Answer:
A. It allows plants to use nitrogen to grow.
Explanation:
However, plants can't directly use nitrogen to grow. The bacteria need to convert atmospheric nitrogen ( N2 gas) into a form that plants can use.
Nitrogen fixation is a symbiotic relationship between plants and microorganisms of nitrogen fixers, which in the process of symbiosis perform the binding of nitrogen, which enters the earth from the air (atmosphere).
It is a reduction process of converting the gaseous form of nitrogen from the air into the ammonia form that is available to plants.

In 1668, Francesco Redi, an Italian scientist, designed a scientific experiment to test the spontaneous creation of maggots by placing fresh meat in each of two different jars. ... Redi successfully demonstrated that the maggots came from fly eggs and thereby helped to disprove spontaneous generation.
The noncyclic pathway is a FLOW of electrons from water, to photosystem II, to PHOTOSYSTEM I to NADPH. Energy is released as ELECTRONS move through the first electron transfer chain. This energy pumps HYDROGEN IONS into the thylakoid compartment, and then they power the formation of ATP as they flow back out. Sunlight provides the energy needed to keep this cycle going.

- Luminous energy is trapped by chlorophyll in Photosystem II.
- When the pigment molecules absorb light, electrons provided by water molecules get in a higher energy level.
- The excited electrons go through the electron transport chain from Photosystem II to a less energetic level in photosystem I.
- <em>When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules. </em>
- Luminous energy absorbed move the electrons from the photosystem I to another electron acceptor, from where they get transported again and used to produce NADPH molecules.
- <em>When electrons leave Photosystem I, they are replaced by new electrons coming from photosystem II. </em>
- When the water molecule breaks down, hydrogen ions remain in the thylakoid lumen, from where they are pumped to the stroma by the ATP synthase.
- The released energy is used to produce ATP molecules.
- Hydrogen ions go back from the stroma to the thylakoid compartment.
The final products are oxygen, ATP, and NADPH.
