Answer:
stages of the nitrogen cycle
1. Nitrogen-fixation
Legume plants such as peas, beans and clover contain nitrogen-fixing bacteria. These bacteria live in swellings in the plant roots called nodules. Nitrogen-fixing bacteria convert nitrogen gas from air into a form that plants can use to make proteins.
Free-living nitrogen-fixing bacteria are also found in the soil. When they die the nitrogen they have fixed into their biomass is converted into ammonium.
2. Feeding
Animals consume plant protein, digest it using specific enzymes and absorb the free amino acids.
3. Production of nitrogenous waste products
Animals cannot store excess protein in their bodies. They break it down and turn it into waste products and excrete them from their bodies.
4. Decomposition
Decomposers (some free-living bacteria and fungi) break down animal and plant proteins (from dead organisms) and nitrogenous waste products to release energy. As a result of decomposition nitrogen is released into the soil in the form of ammonium.
5. Nitrification
A group of free-living soil bacteria called nitrifying bacteria convert ammonium into nitrates in order to obtain energy.
6. Uptake of nitrates
Non-legume plants absorb nitrates from the soil into their roots and use the nitrates to produce their proteins.
7. Denitrification
This is when bacteria in the soil convert the nitrate back into nitrogen gas which then gets released back into the atmosphere.

Explanation:
Carbohydrates consist of single-sugar units called monosaccharides, double-monosaccharide units known as disaccharides and multiple-monosaccharide molecules that make up starches. The predominant purpose of the carbohydrates you eat is to provide fuel to your cells. Disaccharides and starches undergo digestion to reduce them to their individual sugars, and, once absorbed, they travel to the cells and tissues throughout your body to power your physical activities. Proteins consist of 20 different amino acids, mixed and matched to create a vast array of larger molecules that support every process in your body. Digestion of protein results in a pool of single amino acids that your cells incorporate into new proteins as the need arises in your body. These molecules make up muscles and organs, transmit signals between cells, constitute immune molecules, help create the new proteins your tissues require and can serve as a fuel source in a pinch. Your cells contain two types of nucleic acids, ribonucleic acid and deoxyribonucleic acid, or RNA and DNA, respectively. They differ from the other macronutrients in that they are not a source of calories in your diet, and their role is strictly to direct the synthesis of new protein molecules. Made up of units called nucleotides, the nucleic acid DNA contains the genetic blueprint that influences your personal characteristics, while the nucleic acid RNA pulls together amino acids to form new proteins as your cells need them.
