Prairie

PRAIRIE
An ecoysystem is all the biotic and abiotic components of an environment. The prairie is located
in North America. The tempaturevaries greatly and the environment doesn't get enough rainfall to support trees.
One organism in the ecoysystem that adapts well is grass which withstands grazing animals and occasional fires.

Producer: An autotroph organism (grass).
Consumer: Organism that eats producers (caterpillars, bison).
Primary consumer: Organisms that eat consumers (chicken, meadowlark).
Secondary consumers: Organisms that eatprimary consumers (praire felcon, eagle).
Decomposers: Organisms that uses nutrients from dead plants and animals, it starts the chain over (bacteria).

Say that an organism was removed from the web, such as a caterpillar. Though it's not the only grass eating organism it would still mess up the web. Say you put the bison in its place, that part would work, except for the fact that the indigo bunting wouldn't eat the bison. Which would also eliminate that from the food chain and so on.

minerals

Minerals are natural compounds or elements of inorganic nature. There are 92 naturally occuring elements that have specific physical properties, definite chemical composition, and characteristic atomic structure. You can also find between 2,000 to 2,500 minerals in the earths crust. Minerals are formed in a positive response to their environment, most of them to deep for an observer. Environments in which minerals are formed far beneath the earths surface are plutonic igneous, pegmatitic, hot temperature vein, moderate temp. vein, low temp. vein, and a metamorphic environment. Environments in which minerals form near the earths surface are groundwater, weathering, and sedimentary. Minerals are divided into groups on the basis of their composition. About one third of all mineral belong to the group silicates. Other groups are carbonates they includes calcite, oxide which includes magnetite, sulfides which includes pyrite, halides which includes halite, sulfates which includes gypsum, and phosphates whic
he apalite the mineral belongs to. The last group is every mineral that is a chemical element and is found their uncombined state. The elements include copper, silver, gold, and so on.

Impotency The New Therepy

IMPOTENCY: NEW THERAPY

By Tony Gramazio



As many as two-thirds of the men with impotency because of physical conditions, vascular disease, stress, trauma, surgery and diabetes, can probably have an erection again.
A new treatment to help men has been thought to be found. It is less invasive than most other treatments. According to almost 60 medical centers all over the United States of America, the new approach has been found. Transurethral Alprostadil has enabled 64.9% of all men with erectile disfunction to have an erection during sexual intercourse, compared to 18.6% on placebo.
Other therapies include needle injection, vacuum devices, and implants. the new treatment is used by inserting an applicator containing a microspository of aprosital into the urethra after going to the bathroom. When a button on the applicator is pressed the suppository is deposited into the urethral lining. Then after ten minutes an erection is formed
