Why might farmers plant legumes such as peas to improve the nitrogen levels in their soil?

Root nodules are said to house bacteria that are able to fix atmospheric nitrogen. Though nitrogen is abundant in nature, they are in a form of relatively inert gas which plants are not able to utilize. The bacteria living in the root nodules are then fixing the atmospheric nitrogen making them available to plants.

Application of inorganic fertilizer especially nitrogen fertilizer is the common practice of farmers to improve the yield of crops. However, the long-term oversupply of nitrogen fertilizers has resulted in many environmental risks and damages. Thus, farmers are planting leguminous plants such as peas to enhance nitrogen levels in soil and improve crop yield while not imposing risks of environmental pollution.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

i dont know it at allnow im just getting points at this pint
