Early European Farmers (EEF) [a] were a group of the Anatolian Neolithic Farmers (ANF) who brought agriculture to Europe and Northwest Africa.The Anatolian Neolithic Farmers were an ancestral component, first identified in farmers from Anatolia (also known as Asia Minor) in the Neolithic, and outside in Europe and Northwest Africa, they also existed in Iranian Plateau, South Caucasus ...
The Neolithic Revolution, also known as the First Agricultural Revolution, was the wide-scale transition of many human cultures during the Neolithic period in Afro-Eurasia from a lifestyle of hunting and gathering to one of agriculture and settlement, making an increasingly large population possible.

A food pyramid and a corresponding food web, demonstrating some of the simpler patterns in a food web. A graphic representation of energy transfer between trophic layers in an ecosystem. Energy flow is the flow of energy through living things within an ecosystem . [ 1 ]
Map of the spread of farming into Europe up to about 3800 BC Female figure from Tumba Madžari, North Macedonia. The European Neolithic is the period from the arrival of Neolithic (New Stone Age) technology and the associated population of Early European Farmers in Europe, c. 7000 BC (the approximate time of the first farming societies in Greece) until c. 2000 –1700 BC (the beginning of ...
The introduction of the potato also brought about the first intensive use of fertilizer, in the form of guano imported to Europe from Peru, and the first artificial pesticide, in the form of an arsenic compound used to fight Colorado potato beetles. Before the adoption of the potato as a major crop, the dependence on grain had caused repetitive ...
Agriculture was the main economic activity in ancient Mesopotamia.Operating under harsh constraints, notably the arid climate, the Mesopotamian farmers developed effective strategies that enabled them to support the development of the first known empires, under the supervision of the institutions which dominated the economy: the royal and provincial palaces, the temples, and the domains of the ...
The water levels of the river would rise in August and September, leaving the floodplain and delta submerged by 1.5 meters of water at the peak of the flooding. This yearly flooding of the river is known as inundation. As the floodwaters receded in October, farmers were left with well-watered and fertile soil in which to plant their crops.
An expanded three link energy food chain (1. plants, 2. herbivores, 3. carnivores) illustrating the relationship between food flow diagrams and energy transformity. The transformity of energy becomes degraded, dispersed, and diminished from higher quality to lesser quantity as the energy within a food chain flows from one trophic species into ...
