Most nutrients, such as sulfur, phosphorus, carbon, and nitrogen are found within the soil of wetlands.

Most high explosives contain carbon, hydrogen, nitrogen and oxygen atoms and thus comparing their relative abundances of isotopes can reveal the existence of a common origin.

Most emission nebulae are about 90 % hydrogen, with the remainder helium, oxygen, nitrogen, and other elements.

Most azide salts decompose violently to give nitrogen gas as discussed above under applications.

Most present-day vehicles that run on gasoline are fitted with a " three way " converter, so named because it converts the three main pollutants in automobile exhaust: an oxidizing reaction converts carbon monoxide ( CO ) and unburned hydrocarbons ( HC ) to CO < sub > 2 </ sub > and water vapour, and a reduction reaction converts oxides of nitrogen ( NO < sub > x </ sub >) to produce CO < sub > 2 </ sub >, nitrogen ( N < sub > 2 </ sub >), and water ( H < sub > 2 </ sub > O ).

Most plants therefore require nitrogen compounds to be present in the soil in which they grow.

Most plants therefore require nitrogen compounds to be present in the soil in which they grow.

Most of the nitrogen taken up by plants is from the soil in the forms of NO < sub > 3 </ sub >< sup >–</ sup >.

Most Argyle diamonds are classified as type 1a ( see material properties of diamond ), and have low levels of nitrogen impurities, their colour resulting instead from structural defects of the crystal lattice.

Most importantly, the new seeker also introduced detector element cooling in the form of a pressurized nitrogen bottle attached to the launcher.

Most tropical rainforests are located around and near the equator, therefore having what is called an equatorial climate characterized by three major climatic parameters: temperature, rainfall, and dry season intensity Other parameters that effect tropical rainforests are carbon dioxide concentrations, solar radiation, and nitrogen availability.

Most carbenes have a nonlinear triplet ground state, except for those with nitrogen, oxygen, or sulfur atoms, and halides directly bonded to the divalent carbon.

Most diving accidents or illnesses are related to the effect of depth / pressure on gases in the body ; examples are decompression sickness, nitrogen narcosis, oxygen toxicity, arterial gas embolism and CO < sub > 2 </ sub > retention.

Most recharge water enters the rock formations from relatively high ground near the eastern edge of the basin ( in Queensland and New South Wales ) and very gradually flows towards the south and west.

Most excursions take a week sailing off the West Coast of Scotland, but the school also enters into the Tall Ships ' Races annually which allows pupils to take part in an international competition in European waters lasting up to a month.

Most notable is the tradition of shaving one's head when a service member enters the Mediterranean Sea by ship for the first time, known as " Med Head ".

Most other bivalves ingest microscopic phytoplankton as food from the general water supply, which enters via the inhalant siphon and reaches the mouth after passing over the gill.

Most of it was used to build the bridge in Boroughbridge called Peg Bridge, which crosses the river Tutt as it enters the town.

Most notably a few fly by when the Stegosaurus enters the clearing, and one flies out of the dead tree that Kong puts Ann in before he goes to fight the sailors on the log bridge.

Most petroleum enters and exits the plant through pipelines.

Most nitrogen enters the diamond lattice as a single atom ( i. e. nitrogen-containing molecules dissociate before incorporation ), however, molecular nitrogen incorporates into diamond as well.

Most of the Phosphorus enters the lake through non point sources.

Most of Route 1 north of Danville was part of the western division of the Dixie Highway, which goes through downstate Illinois and enters the Chicago area as it passes through Beecher.

Most players with electronic markers use HPA because if CO < sub > 2 </ sub > is used, the marker's electronic Solenoid valve can be damaged if liquid CO < sub > 2 </ sub > enters it.

Most mineral nutrients, on the other hand, are recycled within ecosystems.

Most land plants and land ecosystems rely on mutualisms between the plants, which fix carbon from the air, and mycorrhyzal fungi, which help in extracting minerals from the ground.

Most conspicuous is the absence of decaying dead wood, a crucial component of natural forest ecosystems.

Most ecosystems with a generous supply of termites have a fairly large creature with a very long, thin, sticky tongue for penetrating termite colonies, and powerful forelimbs with heavy claws.

Most land plants and thus, one might say, the very existence of land ecosystems rely on mutualisms between the plants which fix carbon from the air, and Mycorrhyzal fungi which help in extracting minerals from the ground.

Most natural ecosystems experience disturbance at a rate that makes a " climax " community unattainable.

In particular, the species poses a serious threat to the ecosystems of Australia where it was named " The Most Important Pest / Problem ".

Most of the really valuable ecosystems are in relatively shallow coastal waters, above or near the continental shelf, where the sunlit waters are often nutrient rich from land runoff or upwellings at the continental edge, allowing photosynthesis, which energizes the lowest trophic levels.

Most of the world's moorlands are very diverse ecosystems.

Most ecosystems have been to some extent modified or cultivated by human activity for the production of food and income and for livelihood security.

Most importantly, studies have demonstrated that MPAs can be effective at protecting existing kelp forest ecosystems and may also allow for the regeneration of those that have been impacted.

Most of New Zealand's ecosystems have been severely modified by the introduction of land mammals that were not present during the evolution of its ecosystems, and have had a devastating impact on both native flora and fauna.

Most natural ecosystems are nitrogen ( N ) limited and biomass production is closely correlated with N turnover.

Most are bacteria or archaea that live in hostile environments such as deep sea vents and are the primary producers in such ecosystems.

Most Southeastern Asian coastal communities are socially and economically dependent upon coral reef ecosystems.
