The fertile land in Egypt is along the Nile River, called the Nile Valley and the Nile Delta. When the Nile flooded each year, it deposited fertile muds in the valley and delta. The mud was rich and fertile and used to grow wheat and raise cattle. Farming methods included digging irrigation channels from the Nile River and using animal power to raise the irrigated waters.

The Second World War was history's largest and most significant armed conflict. It served as the breeding ground for the modern structure of security and intelligence, and for the postwar balance of power that formed the framework for the Cold War. Weapons, materiel, and actual combat, though vital to the Allies' victory over the Axis, did not alone win the war. To a great extent, victory was forged in the work of British and American intelligence services, who ultimately overcame their foes' efforts. Underlying the war of guns and planes was a war of ideas, images, words, and impressions—intangible artifacts of civilization that yielded enormous tangible impact for the peoples of Europe, east Asia, and other regions of the world.

Explanation:
Not sure how to explain it, except this way.
The further you get away from the middle, the colder it gets, so blue.
The closer you get to the middle, the warmer it gets, so red.
Answer:
competitive exclusion.
Explanation:
When species from the same biological community explore very similar ecological niches, competition among them for less available resources in the environment is instituted. It is common, for example, that plant species whose roots use the same portion of the soil compete for water, minerals and other resources.
Knowing this, Russian biologist Georgyi Frantsevich Gause formulated the Gause principle, or competitive exclusion principle, the theory that ecological niches are unique to each species, and for two or more of them to coexist in the same habitat, it is necessary that their niches have different and sufficient characteristics.
Gause proposed this theory based on several observations that led him to conclude that if two or more species explore exactly the same ecological niche, the competition established between them is so sharp that coexistence becomes impossible. This can cause a loss in species diversity, and that is exactly what Robert Paine observed in his studies.
