Answer:

The correct answer will be Option-1.

Explanation:

Nitrogen fixation is the process by which the atmospheric nitrogen enters the living sphere of the earth. The atmosphere is the largest reservoir of nitrogen in which nitrogen accounts for 78% of the total gases.

The atmospheric nitrogen is fixed through three pathways: lightning, man-made a method like Haber's process and the Biological fixation.

Biological fixation accounts fro 92% of the total nitrogen fixation which is performed by the few bacteria which contains the Nitrogenase enzyme and break down the N₂ to NH₃. The bacteria like<em> Rhizobium</em> is the leguminous bacteria which fixes the nitrogen.

Thus, Option-1 is the correct answer.

select one of the main body systems and explain why it is essential to keep the whole body functioning
tatiyna
Circulatory system: 

--The circulatory system is also known as the cardiovascular system. 
-- It is composed of the heart, blood, blood vessels and also includes the lungs. 

The primary function of the circulatory system to distribute oxygen, nutrients, hormones and other gases to cells of the other body systems. It delivers all the necessary components needed for all the cell activities. Without the circulatory system, we would not be alive. 

It is our blood that carries these necessary nutrients, hormones, and oxygen. All these components trigger certain processes that keep other organs functioning. It also plays a role in eliminating waste by carrying them to the necessary organs that will filter them out. Without a way to dispose of waste, the body will eventually die.
