The bacterium that causes tuberculosis (TB) is Mycobacterium. The specific species responsible for TB is Mycobacterium tuberculosis. This bacterium primarily affects the lungs, causing pulmonary tuberculosis, but it can also affect other parts of the body in extrapulmonary forms of the disease. M. tuberculosis is a slow-growing, rod-shaped bacterium with a waxy cell wall that makes it resistant to many disinfectants and antibiotics. TB spreads through the air when an infected person coughs or sneezes, releasing bacteria-laden droplets. Early detection and appropriate antibiotic treatment are essential to managing and controlling TB. In addition to Mycobacterium tuberculosis, other related species like Mycobacterium bovis can also cause tuberculosis, particularly in animals. The development of the BCG vaccine and advances in antibiotic therapy have significantly reduced TB incidence and mortality rates worldwide.

Bacteria are not able to survive in pickles with excess salt because their protoplasms get shrunk and thus die. This occurs due to the high osmotic pressure caused by the excess salt in the pickles. When bacteria are in a salty environment, water inside their cells moves out to balance the concentration difference between the inside and outside of the cell. This leads to dehydration and shrinking of the bacterial cells, which disrupts their cellular functions and ultimately causes them to die. The high salt concentration acts as a natural preservative by inhibiting the growth of bacteria and other microorganisms, thereby extending the shelf life of pickles and other salty foods. This method of preservation has been used for centuries to prevent spoilage and maintain the quality of food products.

Root nodules are found in some leguminous plants and also in some other plants. In leguminous plants, such as peas, beans, and lentils, root nodules form a symbiotic relationship with nitrogen-fixing bacteria like Rhizobium. These bacteria convert atmospheric nitrogen into ammonia, which is then used by the plant for growth. This mutualistic relationship enhances soil fertility and supports agricultural productivity. Besides legumes, a few other plants, such as some species of alder and actinorhizal plants, also form root nodules with different types of nitrogen-fixing bacteria like Frankia. These nodules play a similar role in nitrogen fixation, contributing to the nitrogen cycle and improving soil quality. Root nodules are essential for sustainable farming practices and ecosystem health by providing a natural source of nitrogen to plants.
Nitrogen-fixing bacteria are those that directly convert atmospheric nitrogen into nitrogenous compounds.

Nitrogen-fixing bacteria are those that directly convert atmospheric nitrogen into nitrogenous compounds. These bacteria, such as Rhizobium and Azotobacter, establish symbiotic relationships with the roots of certain plants like legumes, enabling them to fix nitrogen from the air into a usable form like ammonia. This process is vital for plant growth and agricultural productivity, as it provides an essential nutrient for plant development. In addition to symbiotic nitrogen-fixing bacteria, there are also free-living nitrogen-fixing bacteria found in soil and water that contribute to the nitrogen cycle. These bacteria play a critical role in maintaining soil fertility and supporting ecosystems. Their ability to convert nitrogen into compounds that can be assimilated by plants helps sustain food chains and biodiversity. Nitrogen-fixing bacteria are an important part of sustainable agriculture and environmental health.

The smallest organism among the options provided is the virus. Viruses are much smaller than bacteria, mycoplasma, and yeast. They are submicroscopic infectious agents, ranging in size from about 20 to 300 nanometers. Viruses cannot replicate on their own and must infect a host cell to reproduce. They consist of genetic material (either DNA or RNA) enclosed in a protein coat called a capsid. Some viruses also have an outer lipid envelope. Viruses are known to infect a wide range of hosts, including animals, plants, fungi, and bacteria. Due to their small size and ability to mutate rapidly, viruses pose significant challenges in the development of treatments and vaccines. Despite their small size, viruses play important roles in evolution and the ecosystem, but they can also cause serious diseases in humans, animals, and plants.
