It doesn't do so directly. The poop breaks down and creates ammonia and mulm. This ammonia is deadly poisonous but nature has contrived to fix it by converting it into Nitrite and then to Nitrate by using naturally occurring bacteria in the environment and the 'cycled' filter. The plants can then use up the nitrate and mulm as they photosynthesise and grow.
