Plants and animals could not live without nitrogen. It is an important part of many cells and processes such as amino acids, proteins, and even our DNA. It is also needed to make chlorophyll in plants, which plants use in photosynthesis to make their food and energy.
Nitrogen is an important component of many essential structural, genetic and metabolic compounds in plant cells. It is also an elementary constituent of numerous important organic compounds including amino acids, proteins, nucleic acids, enzymes, and the chlorophyll molecule.
Of all the essential nutrients, nitrogen is the one that is most often limiting for crop growth. Nitrogen is the nutrient which normally produces the greatest yield response in crop plants, promoting rapid vegetative growth and giving the plant a healthy green color.
Because it has to be that way
Genetic engineering is the
direct treatment of an organism’s genome using biotechnology. It is a set of
technologies used to alter the genetic makeup of cells, together with the
transport of genes within and across species boundaries to produce improved
organisms. An example would be to
protect plant from insect damage, it can be made into a transgenic plant.
Transgenic plant are called genetically modified organisms (GMO) because there
is a gene added or removed in the original plant to obtain a set of
characteristic such as insect damage.
Answer:
The answer is D. Digestion
in the earth's atmosphere is made up about approximately 78 percent nitrogen and 21 percent oxygen.
