FOOD CHAİN

                                 
 In nature,animals fed on each other.They become energy for other kinds.For food chain sun is the begining of everything, it's the endless energy source.It give it's energy to producer(grass) and primary consumer(grasshopper) with fedding on producer, it takes energy from it.And it becomes the food for secondary consumer(snake),gives its energy to it.Than,tertiary consumer(hawk) fed with secondary comsumer.These animals eaten by the other animals, again transferring energy and organic compounds from one animal to another.
  This chain of energy transferring from one species to another can continue several more times, but it eventually ends. It ends with the dead animals that are broken down and used as food or nutrition by bacteria and fungi. As these organisms, referred to as decomposers, feed from the dead animals, they break down the complex organic compounds into simple nutrients. Decomposers play a very important role in this world because they take care of breaking down (cleaning) many dead material. There are more than 100,000 different types of decomposer organisms! These simpler nutrients are returned to the soil and can be used again by the plants. The energy transformation chain starts all over again.

Ephesus

  Ephesus was an ancient Greek city, and later a major Roman city. It was one of the twelve cities of the lonian league during the Classical Greek era. In the Roman period, Ephesus had a population of more than 250,000 in the 1st century BC, which also made it one of the largest cities in the Mediterranean world.The city was famed for the Temple Of Artemis which is one of the Seven Wonders Of the Ancient World.Emperor 1.Constantine rebuilt much of the city and erected new public baths.Following the Edict of Thessalonica from emperor 1.Theodosius, the temple was destroyed in 401 AD by a mob led by St. John Chrysostom.The town was partially destroyed by an earthquake in 614 AD. The city's importance as a commercial center declined as the harbor was slowly silted up by the Cayster River.
Ephesus was one of the seven churches of Asia that are cited in the Book of Revelation.The Gospel of John may have been written here. The city was the site of several 5th century Christian Councils, see Council of Ephesus. It is also the site of a large gladiators' graveyard.
Today's archaeological site lies 3 kilometers southwest of the town of Selçuk, in the Selçuk district of İzmir Province, Turkey. The ruins of Ephesus are a favorite international and local tourist attraction.
