Which of the following statements about ecosystems is not true?
a. ecosystems include living and nonliving things.
b. temperature and climate are not part of an ecosystem.
c. an ecosystem can be as small as a rain puddle.
d. sunlight, air, and water can be parts of an ecosystem.

b. temperature and climate are not part of an ecosystem.

Explanation:

Ecosystem refers to the interaction between the living component and non-living components of a community. Ecosystem can be in different habitats including terrestrial, aquatic etc. It is worthy to note that ecosystems vary in its size; it can be small like the rain puddle that was mentioned in the options ans it can also be as large as the largest rainforest in the world.

The non-living components, also called abiotic components of an ecosystem include nutrients, climate, temperature, soil, water, air, sunlight etc while the living or biotic components include all organisms that possess life in them e.g plants, animals, microbes etc.

Therefore, the statement that temperature and climate are not part of the ecosystem is FALSE because they are part of the abiotic components of the 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.
