Food Chain

We food chains use in ecological modeling.Food chains are from 3 or more levels.Food chanis are consisting from a plant and animals. A food chain differs from a food web, because the complex polyphagous network of feeding relations are aggregated into trophic species and the chain only follows linear monophagous pathways. A common metric used to quantify food web trophic structure is food chain length. In its simplest form, the length of a chain is the number of links between a trophic consumer and the base of the web and the mean chain length of an entire web is the arithmetic average of the lengths of all chains in a food web.When rats eat a plnt , snakes rats,eagles snakes than we eat that eagle.
Plants et energy from SUN, e making sugous and it calls photosyntes.

Chocolate

One of my favourite foods is chocolate.I love it very much.

One day I wanted to make a chocolate with my sister but it wasn't so tasty like in shops :( 

In our English class we ate a Belgian chocolate and it was so tasty.

Chocolate has positive and negative sides:

Positive

• Cocoa or dark chocolate may positively affect the circulatory system
• There is some evidence that eating chocolate can help reduce the risk of certain cardiovascular problems and also reduce blood pressure in both overweight and normal adults.
• Chocolate may boost cognitive abilities.
• Dark chocolate may lower cholesterol levels in adults. Although basic research has provided preliminary evidence that polyphenols in chocolate might inhibit oxidation of LDL cholesterol, few results from clinical trials are conclusive about such an effect in humans.
• According to one study, chocolate consumption correlates with lower body mass index.
• Other possible effects under basic research include anticancer, brain stimulator, cough preventor and antidiarrhoeal activities.
• Cocoa beans contain a large amount of chemicals called flavonoids. Some scientists believe that these flavonoids can be used to create natural supplements to ease diarrhea symptoms. Dark chocolate contains high concentrations of cocoa and may offer mild relief.

Negative

• Chocolate is believed to cause heartburn because of one of its constituents, theobromine, relaxes the oesophageal sphincter muscle, hence permitting stomach acidic contents to enter into the oesophagus.Theobromine is also toxic to many animals because they are unable to metabolize it (see theobromine poisoning).
• The unconstrained consumption of large quantities of any energy-rich food, such as chocolate, without a corresponding increase in activity, increases the risk of obesity. Raw chocolate is high in cocoa butter, a fat which is removed during chocolate refining, then added back in varying proportions during the manufacturing process. Manufacturers may add other fats, sugars, and milk as well, all of which increase the caloric content of chocolate.
• Chocolate and cocoa contain moderate to high amounts of oxalate, which can cause some health concerns particularly for individuals at risk for kidney stones.
• Chocolate absorbs lead from the environment during production, and there is a slight concern of mild lead poisoning for some types of chocolate. In a study from Nigeria, the average lead concentration of cocoa beans was less than 0.5 ng/g, among the lowest reported values for a natural food, with lead concentrations ranging from 70–230 ng/g for raw and processed cocoa.These measurements "are consistent with market-basket surveys that have repeatedly listed lead concentrations in chocolate products among the highest reported for all foods. One source of contamination of the finished products is tentatively attributed to atmospheric emissions of leaded gasoline, which is still being used in Nigeria.the figures are still comparatively low when compared to 200,000 ng, which is the WHO tolerable daily limit for lead consumption.
• Research on elderly people showed chocolate might cause osteoporosis.
• A few studies have documented allergic reactions with chocolate in children.
• There is some evidence that chocolate may be addictive.

Computer games

Computer games have two sides: bad and good.

Bad sides                                     Good sides

   

 it spoils eyes                               children have fun

 it emits children                         children are interested in all of the games

                                      

I know many computer games that I like but most of all I love The Sims.It is a game about a life:you can build a house,you can play with more than one person,your character.Your character will be a child then he/she will get older.There are 4 seasons.

I love a game site too.It is http://www.friv.com.There are more than 100 games.I play all of them.

My favorite TV show

My favorite TV show is The Voice or The Voice kids.These shows are about singing.People come and sing on the stage.There are 4 trainers.If  person sings well one or more trainers press the button and turn. If  more than one trainer turns towards the singer,  the singer chooses one of the trainers.there are 4 pools. The shows are same but in The Voice kids there are singing only children.I wachted every episode of The Voice of Armenia but I liked season 2 final.I voted many times and win my favourite singer!I was very happy and now I'm following The voice season 3.
I watched The Voice of Australia kids and won my favorite singer too.I think she will become a great singer.

If I have a time machine...

If I have a time machine I will go past and future.If I go past I will go to Leonardo Da Vinchi and ask a question:why he drew Mona Liza so long?,who is Mona Liza? and why he drew her?.
If I go to the future I will go to 2050 year and see what will there be?,will there be robots? and see what nature will be?
I think that there will be a day when scientist wil make a time machine :)

To live long you must

I think that the most important thing to make our life longer is to be healthy and live in country where is clean air.If you do exercises every morning you will be healthy.Than it's to have money but not very much,eat but not too much to be fat and eat vegetables and fruits,sleep and be happy with friends.i do all to  live long:I have fiends in school and in our street,I eat healthy thing,do exercises.But I don't live in a country where is clean air :( 

Halloween

Halloween also known as Allhalloween, All Hallows' Eve or All Saints' Eve.People celebrate it in 31 October.It celebrate very gorgeous in USA,France,Great Britain,Ireland and in Canada.It came from Scotland.Samhain was the first and most important of the four quarter of days in the medieval Gaelic calendar and was celebrated in Ireland, Scotland and the Isle of Man.Children wear scary masks and costums.They go homes and say "trick or treat".People give them sweets or not.If they choose trick and don't give them sweets they can do scary jokes.In that day some people dig pumpkins,put inside candles and put it outside up to morning.In this year in Armenia we celebrate it in Vahagni.Some guys come with scary masks,bags for sweets and there was a big party.
