They ensure they leave the system and they also ensure that people get the nutrients they need.
When humans farm large plantation of one cash crop, they reduce the biodiversity of the region because they reduce the genetic diversity of the species in the environment. A reduction in genetic diversity means that the genetic variability of the species is reduced hence there are fewer sub-species in the environment. This ultimately reduces the biodiversity of the ecosystem - which is the variability among all the living organisms in the environment.
Two diverse species naturally breed an offspring, and selective preserves raver new traits in a given environment, (they evolve).
