Do all organisms have a digestive system and why?

No. plants do not digest food, they make their own from sun-light, water, CO2, and soil minerals. Plants don't need a digestive system. Animals, in other words, do.I think plants are the only organisms that don't have a digestive system. Many species of the Protists never developed a digestive system. Some unsegmented worms that have taken up a parasitic livelihood (such as Hook Worms and tape worms) have lost what digestive they once had and absorb their nutrients directly through their skin.

What effect does the sympathetic and parasympathetic nervous system have on the digestive system?

The parasympathetic nervous system is a division of the autonomic nervous system (along with the sympathetic nervous system, and the enteric nervous system). In simple terms, the SNS can be thought of as the body's gas pedal, and the PNS as the brake. So where the SNS deals with 'fight or flight' the PNS deals with 'rest and digest'. In other words, the PNS is often inhibitory. For example, it can act to slow down heart rate, enhance the peristaltic contractions of the gut, or increase secretions of digestive enzymes. In can also cause vasodilation (make the blood vessels wider) around your gut after meals: this means more blood flows to your intestive and stomach after you've eaten a meal, allowing you to digest what you've eaten.
