Middle Ages, the period in the history of Europe that lasted from about AD 350 to about 1450. by the end of the middle ages, many Modern Europeans states had taken shape. The term middle ages was invested by people during the renaissance, a period of cultural and literary change in the 13th, 14th and 15th centuries. During the Renaissance, people through that their own age and the time of ancient Greece and Rome were advanced, sophisticated enlightened and civilized the adjective medieval comes from the Latin words for this term, medium (middle) and aevum (age).
Modern cities grew out of medieval ones. Although ancient cities had existed before the middle ages, they had been centers of political and religious life, not centers of commerce. Medical clinics, in contract, were primarily commercial. They were supported by trade, exchange, production, consumption and moneymaking. Many of the sorts of businesses that exist today, such as banks and corporation, can map out their ancestry to the middle ages. The history of the middle age (13th, 14th and 15th century) is a story of ceaseless borrowing, adaptation and change with aggrandizement in various pre-requisite of development.

An ecosystem is a community of living organisms in conjunction with the non-living components of their environment (things like air, wider and mineral soil), interacting as a system. Ecosystem is a natural unit which consists of biotic communities and their abiotic environment. It is also Basic functional unit in ecology. Energy, water, nitrogen and soil minerals are other essential abiotic components of an ecosystem. Ecosystem are controlled both by external and internal factors. External factors such as climate, parent material that forms the soil, typography, etc. and internal factors include disturbance, succession and the types of species present.
Characteristics of Ecosystem:
i) Biotic component: producer (green plants), consumers (animals), decomposers (microorganisms)
ii) Abiotic component: Air, water, soil
iii) Energy flow: Sun is the main source of energy
iv) Matter
v) Interrelationship
vi) Biological integration
vii) Flexibility
viii) Ecological regulation
ix) Smallest unit of biosphere
x) An open system with a continuous, but variable influx and loss of materials and energy.
