Drag each tile to the correct box. Arrange these steps in the nitrogen cycle in the correct order to explain how nitrogen from the atmosphere cycles through the other spheres on Earth. biosphere, dead organic mater, nitrogen fixation, denitrification, ammonification, nitrification yielding nitrate, nitrification – yielding nitrite

1) dead organic matter

2) ammonification

3) nitrification – yielding nitrite

4) nitrification yielding nitrate

5) denitrification  

6) biosphere

7) Fixation

Explanation:

The atmosphere is the principal reservoir of nitrogen. There are few organisms, such as bacteria, capable of fixating it. To the moment, no eukaryotic organisms have been found to fixate nitrogen.  

There are three principal stages in the nitrogen cycle:

- ammonification: the process by which nitrogenated components found in the soil, product of decomposition of organic matter, are degraded to simpler components by bacteria and fungus. These microorganisms metabolize these compounds and release the excess of nitrogen as ammoniac NH3 or ammonia NH4. Basically, ammonification is the nitrogen conversion from the amino or imino groups (as it is found in organic matter), to ammonia.  

- nitrification: The process by which many bacteria in the soil are capable to oxidate the ammoniac or the ammonia. This is an energy generator process. The energy released is used by these bacteria as a primary source of energy. A group of bacteria oxidates the ammoniac or ammonia to nitrite and another group of bacteria oxidates nitrite to nitrate. Nitrification results from the sequential action of these two groups.

the combination os ammonification and nitrification gives a new form of nitrogen that is assimilable by plants.

- assimilation: The process by which plants take nitrogen from the soil and put it into circulation in the trophic chain.

When plants and animals die, their tissues are processed by microorganisms that give nitrogen back to the soil. And so the cycle starts all over again.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
