Answer:
The Ecosystems that show where early civilization occurred are Savannah and Rain forest Ecosystems because the areas allowed people to grow crops even during the time of little rainfall.
Explanation:
Savannah Ecosystem actually started as rainfall inadvertently reduced around the tropics during the olden days especially between 66 million to 25 million years ago according to various resources available. The most dominant vegetation in the Savannah nowadays are grasses apart from the covered trees. Even the grasses must have appeared about 50 million years ago although there may be some possibility that some Ecosystems like Savannah may have existed earlier than that. From various online resources, it is evident that the first human to appear on earth may have appeared in the SAVANNAH REGION of Africa after which he ensure various resources in the environments were modified before moving and spreading to other continents.
However, the Rain forest region is the ecosystem that usually occur in high annual rainfall areas all around the earth.The trees are of broad leaves and always evergreen. The ares are mostly with one river or the other e.g Nile River, Amazon River, Congo River. This Ecosystems must have been in existence for over 500 million years according to various researches thus giving credibility to the fact that it is among the two Ecosystems that ensure early civilization all year round just like Savannah Region with low level of rainfall then.
After the fall of the Berlin Wall the nation which broke up into many independent states was Yugoslavia. Before the fall of the Berlin Wall, Yugoslavia was just one country in southeastern Europe, but after the fall of the Berlin Wall, the country was divided into different socialist republics being: Bosnia and Herzegovina, Croatia, Macedonia, Montenegro, Slovenia and Serbia.
In 1775 when the American Revolution began, the British and Americans had one of the most important battles at Fort Ticonderoga. Here the British Military base was attacked, and the capture of the fort became the first American victory. It boosted the morale of the Continental Army and would be a significant factor in the outcome of the revolution.
The colonists hoped that Fort Ticonderoga could stop the British Army from proceeding to the South.
The Fort had critical importance ranging from Ammanents that Americans had short of supply and had a collection of massive artillery (howitzers, cannons, and mortars).
The Forts location at the shores of Lake Champlain was also a strategic route to the British controlled provinces in the North and route along the thirteen colonies.
