I think it is called the METAMORPHIC ROCK.
It formed not only when the pressure changes but also with the heat.
Good luck :)
Polyallelism.
Poly means many. So, when there are more than two alleles for the same gene locus we call it of polyallelism. This makes genetic variability much bigger because there are several alleles for a possible location in a chromosome and this would make, for example, from two parents a possible combination of two out of four possible alleles if between them they had all different alleles.
<u>Answer</u>: A food web is a graphical representation of interconnected food chains.
A desert food web will have as producers the cacti, annual flowers and sagebrush. Some of the primary consumers of these food web are the ants, lizards and pronghorn.
Secondary consumers are the scorpions, snakes and wolves. The haws represent tertiary consumers and in some instances they may even eat wolves, especially unprotected cubs.
The energy flows through the food web from inorganic components such as the sun, nutrients, water into the producers. Then primary consumers eat the producers and are in turn eaten by the secondary consumers. The tertiary consumers will feed on both primary and secondary consumers.
<u>Notes</u>:
Please find attached all the necessary files with the exception of the desert flowers (due to maximum numbers of attached files restriction). These images are not copywrighted and thus free to use.
I have created the required table as an Excell document in case you need to modify it. I did not add the images for the species in the Excell table.
I have also created a more exensive food web (described in the Answer section) for your desert habitat.
As I had some difficulties in understanding the last part of your question, please let me know in a comment if you require additional modifications. I have saved the foodweb PSD file as well as he Excell file.

The correct answer is - isobar.
On this map, the lines represent isobars. The isobars are lines that closed and circular, connecting the dots of places that have the same air pressure. On this map, as we can see, is represented the air pressure in the United States.
From what can be seen on this map, the air pressure in the western part of the country is high air pressure, throughout all of that half of the country. The eastern half is more mixed, with the isobar marked with 1016 being the areas with high pressure, while all the others are low air pressure zones.
