The idea right now is that they both have some influence on perception.

Nature is the biological make up but it is effected by the environment (Nurture).

Nature has more to do with genetics and evolution while nature is the environment.

An example of nature and its effect on perception would be certain species of spiders and bats that live in dark caves underground and after several generations they become blind since there is little use for vision in the dark yet their hearing and other senses are boosted.

An example of nurture would be an experiment done on cats who were put in artificial environments with wavy lines everywhere so ground, walls, and sky could not be distinguished grew up adapting to the artificial environment but had a hard time navigating in a natural setting such as in the woods or a field.

Both influence the outcome of psychological processes. The exact degree that genetics affects [insert psychological process here] is identified in [insert body of studies here/yet to be discovered].

You do realize that there is a massive amount of scientific work on this topic, right?
