glucose/ carbohydrates
Plants use sugars produced during photosynthesis to make organic compounds. Photosynthesis is a plants method of making food for itself.
Three other elements that make up most organic compounds are: 1. NITROGEN 2. HYDROGEN 3. OXYGEN
Carbon, Nitrogen, Oxygen, and HydrogenRead more: http://wiki.answers.com/What_four_elements_are_found_in_organic_compounds#ixzz1BXmelfRK
Plants can not absorb atmospheric elemental Nitrogen (N2). The nitrogen must be bound to carbon or hydrogen atoms such as ammonia (NH3), or Urea (NH2)2CO. Nitrogen Fixing Plants such as clover have a symbiotic relationship with bacteria on their root system that convert atmospheric nitrogen (N2) to forms that the plants can use.
Nitrogen is found in plants and animals, though mainly plants as a way to more easily have photosynthesis occur. It is found in the blood of the organisms in which have nitrogen in their bodies.
To make organic compounds
"plants"
Plants use sugars produced during photosynthesis to make organic compounds. Photosynthesis is a plants method of making food for itself.
Autotrophic organisms are plants that don't need an exogenous supply of organic nutrition. Autotrophic organisms make their food from inorganic compounds, e.g. nitrogen.

You can make most organic compounds with just 4 elements: carbon, hydrogen, oxygen and nitrogen.
when animals eat plants,they get nitrogen compounds that their bodies need.plants do not make these nitrogen compounds. so from where do plants get their nitrogen compounds/ from the air
Many compounds in plants include Nitrogen including Proteins and DNA. Note, most plants can not use atmospheric Nitrogen (N2), and must absorb nitrogen that is bonded to hydrogen or carbon such as Ammonia (NH3).
Plants are able to use simple nitrogen compounds from the soil, such as ammonium and nitrate, to synthesize proteins and other complex compounds through a process called nitrogen assimilation. This involves incorporating the nitrogen into amino acids, which are the building blocks of proteins, through a series of biochemical reactions in the plant cells.
Nitrogen fixing bacteria, such as Rhizobium.
Herbivores can directly increase nitrogen mobility by increasing the quality of organic matter entering the decomposition cycle, but they also may decrease nitrogen mobility by decreasing the biomass of high-nitrogen species in the plant community.
Free nitrogen means chemically free, it has not combined with any other elements. Fixed nitrogen has combined to make ammonium compounds or nitrate compounds which can be easily absorbed by plants and used to make amino acids in the plant cells.
