Question

"Helps fix nitrogen in soil. Boost pea and bean yields with Garden Soil Inoculant. Simply shake granules into furrows as you plant. It contains nitrogen-fixing bacteria to promote stronger root systems and larger harvests. Easy-to-use sprinkler top makes application a snap. 8.7-oz. container treats a 150' row." This product is recommended for growing plants such as beans and peas, for all of the following reasons EXCEPT: These plants can convert nitrogen gas to ammonia

                These plants can convert nitrogen gas to ammonia

                These plants form symbiotic relationships with bacteria in the product.

                These plants are legumes.

                These plants produce root nodules that harbor bacteria.

Molecular nitrogen (nitrogen gas) makes up 78% of the Earth’s atmosphere, but is unavailable for use by all organisms except for some nitrogen-fixing ____. (Choose all correct answers.)

                bacteria

                cyanobacteria

                eukaryotes

                prokaryotes

                fungi

                Protists

Nitrogen gas is a chemically inert molecule. The prokaryotes that fix-nitrogen produce the enzyme nitrogenase. What does this enzyme do that allows these organisms to use nitrogen gas? (Hint: You might want to consult a chemistry book to help you with this answer.)

In biological nitrogen fixation (N2, ammonia, hydrogen, oxygen), is (Reduced, oxidized) when it accepts atoms, resulting in the production of (nitrogen gas, nitrate, water, ammonia ) .

Legumes produce (nitrogen, nitrogenase, lehemoglobin,oxygen ,bacteria) , which regulates the amount of (nitrogen, nitrogenase, lehemoglobin,oxygen ,bacteria) present in the root nodule so (nitrogen, nitrogenase, lehemoglobin,oxygen ,bacteria) activity is not inhibited.

Humans and other animals acquire their nitrogen from which of the following? (Choose all correct answers.)

                protein from animals that eat other animals

                protein from animals that eat plants

                plant protein

                protein from legumes

The nitrogen sources used by humans are (organic, inorganic) componds, while nitrogen gas is an (organic, inorganic) compound.

Explanation / Answer

Molecular nitrogen is converted into ammonia in legumes by N fixing bacteria.

Plants are leguminous and develop root nodules by infection of these bacteria and develop symbiotic relationship and plant harbour these bacteria.

Prokaryotes like cynobacteria and bacteria fix atmosphere nitrogen. Thus Prokaryotes, bacteria and cynobacteria are correct options. Fungus and protists are not correct answer.

Humans and other animals acquire proteins, depends upon trophic level in food chain. Herbivores acquire proteins from plant. And carnivorous acquire proteins from animals. And omnivorous acquire proteins from both plants and animals. Thus first three options are correct. Legumes supply ammonium ions to plants not proteins.

Nitrogen used by plants is organic and nitrogen gas is inorganic.
