nitrogen fixation
It is called nitrogen fixing.
A substance that speeds the changing of food into a usable form* is called an enzyme. More generally, in any chemical context, a substance that speeds a reaction without itself being changed is called a catalyst._______________________________________*This changing of food into a usable form is called "digestion".
The process of changing free nitrogen gas into a usable form of nitrogen is called nitrogen fixation. This can occur through biological processes involving nitrogen-fixing bacteria, or through industrial processes like the Haber-Bosch process.
The process of changing nitrogen gas into a usable form of nitrogen is called nitrogen fixation. This can be done by both biological means, such as through nitrogen-fixing bacteria or through non-biological methods like the Haber-Bosch process which is used to make ammonia.
It converts energy in food into a more usable form. (Cellular Respiration-The enzyme-controlled process in which energy is released from food and converted into a form that the cell can use.)
Digestion is the process of breaking down food into usable materials, and is one function of the digestive system. The other function, absorption, makes these materials available to all cells in the body.
That is the process known as cellular respiration.
Nitrogen fixation is the process in which certain bacteria in the soil or root nodules of leguminous plants convert free nitrogen gas (N2) into a usable form such as ammonia (NH3) or nitrate (NO3-). This conversion allows plants to take up the nitrogen they need for growth and development.
It converts energy in food into a more usable form. (Cellular Respiration-The enzyme-controlled process in which energy is released from food and converted into a form that the cell can use.)
Food is broken down into usable forms in the digestive system through the process of mechanical digestion (chewing and churning) and chemical digestion (enzymatic breakdown of molecules). This allows nutrients to be absorbed across the walls of the digestive tract and into the bloodstream for use by the body.
