The Homestead Act of 1862 provided that any adult citizen (or person intending to become a citizen) who headed a family could qualify for a grant of 160 acres of public land by paying a small registration fee and living on the land continuously for five years. If the settler was willing to pay $1.25 an acre, he could obtain the land after only six months’ residence.
But the law did not provide the new beginning for urban slum dwellers that some had hoped; few such families had the resources to start farming, even on free land. The grants did give new opportunities to many impoverished farmers from the East and Midwest, but much of the land granted under the Homestead Act fell quickly into the hands of speculators. Also, over time, the growing mechanization of American agriculture led to the replacement of individual homesteads with a smaller number of much larger farms.

Mutualism refers to the ecological interaction between two or more species in which each species benefits. Mutualism is a type of ecological interaction that occurs frequently. Most vascular plants have mutualistic interactions with mycorrhizae, flowering plants are pollinated by animals, vascular plants are dispersed by animals, and corals have zooxanthellae, among many others. Mutualism contrasts with interspecific competition, in which each species loses fitness, and exploitation, or parasitism, in which one species gains at the "expense" of the other.
Mutualism is frequently confused with two other ecological phenomena: cooperation and symbiosis. Cooperation most commonly refers to increases in fitness caused by within-species (intraspecific) interactions, but it has also been used (particularly in the past) to refer to mutualistic interactions, and it is sometimes used to refer to non-obligate mutualistic interactions.
