Екосистема – це сукупність організмів різних видів та середовища їхнього існування, що пов'язані обміном речовини, енергії та інформації. Домашній акваріум, озерце, край села, степовий вибалок, лісовий масив, ціла наша планета – все це екосистеми єдиної біосфери. Поняття "екосистема" запропонував у 1935 році А. Тенслі. Функціонування екосистеми забезпечує "внутрішній" біологічний колообіг речовин між абіотичною та біотичною частинами. Екосистеми є відкритими біосистемами, і тому для існування в часі потрібні "зовнішні" потоки енергії, речовини та інформації в складі загального геологічного колообігу.

Cathedral of Pokrov or St Basil the Blessed

The story of St Bazil’s Cathedral begins in May 1552. Red Square then was the site of mass prayers on the eve of the departure of the tsar and his armies to fight the Khan of Kazan. Mingling in the crowd was a barefoot holy man dressed in rags, well known to the crowd as Basil the Blessed for his [32] . Only traditional immunity [33] to such holy men in Russia could save him from Ivan the Terrible’s wrath. Even before Ivan IV unleashed his reign of terror, Basil was [34] the tsar that his future would condemn him to eternal damnation. Before the departure for Kazan he also predicted that the tsar would murder his first-born son. Basil died [35] Ivan was laying siege to Kazan. His body was buried on the future site of the cathedral, named to [36] the victory.
It took six months for the Russians to force their way into the Kazan fortress. Victory came on 1 October 1552, which, according to the Orthodox calendar, was the feast of Pokrov, or protection of the Blessed Virgins Veil. Thankful for the help of the Virgin, the young monarch ordered a wooden church to be built in Red Square.
As more military success followed, a series of wooden chapels [37] shape around the already existing Trinity Church. Finally there were seven victories and seven new churches in Red Square. Later all them were torn down to make the way for the Cathedral of Pokrov — better [38] as St Basil’s Cathedral — that was to surpass in size and splendor anything the Russian rulers had built before.
