<u>The four types of interactions in communities are:</u>
- Mutualism
- Parasitism
- Commensalism
- Competition
<u>Definition of each interaction:</u>

The type of interaction in which both the species involved are benefited, it is called mutualism.
<em>Parasitism:</em>
The type of interaction in which one species is benefited, whereas the other is harmed, it is called parasitism.

The type of interaction in which one species gets benefited without harming or providing benefits to others is called commensalism.
<em>Competition:</em>
The type of interaction in which both species lose is called competition. It is opposite of mutualism.

Answer:
Most nerve fibers from both divisions innervate many of the same effectors.
Most nerve fibers from both divisions share the same sites of origin.
The parasympathetic nervous system is responsible for controlling the homeostasis, resting and digestion functions of the body. The sympathetic nervous system controls the body's response against threat and fight and flight responses. Both parasympathetic and sympathetic nervous systems are responsible for the involuntary functions of the human body.
Most nerve fibers from both divisions share the same sites of origin because both have the nerve fibers that are originated from brain or spinal cord that are directed or passes to the targeted organs.
Most nerve fibers from both divisions innervate many of the same effectors so as to induce functions according to the bodily needs.
