Iwill mark as the brainliest answer 1c what was the most important factor in making mesopotamia’s farmland fertile? 2a why did farmer’s need to develop a system to control their water supply? 2b in what ways did a division of labor contribute to the growth of the mesopotamian civilization? 2c how my managing large projects prepare people from running a government? 3. farmers who used the rivers for irrigation were part of a cause-effect chain. use a chart like this one to show that chain.

1c: Every year, floods on the Tigris and Euphrates rivers brought silt to the land. The fertile silt make the land good for farming.

2a: This region received little rain. When a lot of rain fell onto the rivers higher up, water levels got very high. Flooding would destroy crops, kill livestock, and wash away homes. When water levels were too low, crops dried up. They developed irrigation.

2b: Because of irrigation, they had a surplus of food (more than enough). Fewer people were needed to farm. People who quit farming began to become crafters, religious leaders, and government workers. They were able to accomplish more.

2C: Managing large projects helps with organization and to complete these types of projects the Mesopotamians needed structure and rules.

3: River levels were uneven -> irrigation water deficit ->  malnutrition -> river levels balanced -> people enjoy many foods

those sounds of the natural world are bioacoustics, and they're more than a false-color spectrogram of data from the musiamunat conservation area.
