The number of different species in an area is called the area’s biodiversity

One reason to preserve biodiversity is that wild organisms and ecosystems are a source of beauty and recreation. In addition, biodiversity has both economic value and ecological value within an ecosystem. Many plants, animals and other organisms are economically valuable to humans. Also, all the species in an ecosystem are connected to one another.

A keystone species is a species that influences the survival of many other species in an ecosystem.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
