The climate of the south lent itself to farming on ?

Plantations

Explanation:

The climate of the South was particularly conducive to farming on plantations. Plantations were large expanses of land that were farmed in an intensive way. These plantations grew cash crops such as indigo, cotton and tobacco. In order for these enormous plantations to be worked efficiently, slave labor was used. This was one of the main reasons for the economic success of the region.

while it was true that the cotton gin reduced the labor of removing seeds, it did not reduce the need for slaves to grow and pick the cotton.

explanation:

before eli whitney's invention of the cotton gin, picking and cleaning cotton was a slow, labor-intensive job. workers, usually slaves, had to pick the seeds from the cotton fibers by hand. this invention made it possible to grow large amounts of cotton on big farms and make money.
