Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Plants and animals need nitrogen to make ____
A
Protein and Nucleic Acids
B
Carbohydrates
C
Lipids
Explanation: 

Detailed explanation-1: -Once nitrogen is converted into compounds like ammonium and nitrate, these can be taken up from soils by plants and then the nitrogen can be used to form macromolecules like proteins and nucleic acids (DNA and RNA). Nitrogen is a crucially important component for all life.

Detailed explanation-2: -All living things need nitrogen to build proteins and other important body chemicals. However, most organisms, including plants, animals and fungi, cannot get the nitrogen they need from the atmospheric supply. They can use only the nitrogen that is already in compound form.

Detailed explanation-3: -Nitrogen is an essential nutrient for the production of amino acids, proteins, nucleic acids, etc., and stone fruit trees require an adequate annual supply for proper growth and productivity. Nitrogen is primarily absorbed through fine roots as either ammonium or nitrate.

Detailed explanation-4: -Nitrogen is required by plants to produce amino acids, proteins, and DNA. Nitrogen is necessary because it is a component of chlorophyll.

Detailed explanation-5: -Nitrogen is needed both by Plants and Animals because it is the major constituent of proteins, vitamins, hormones, etc. Nitrogen is a crucially important component of life. It is an abundant element present in the atmosphere.
