<span>Both are called accessory organs, meaning they work together
with the GI tract to break down food. The liver is responsible for producing a
green fluid called bile that breaks down fats absorbed by the body. They are
responsible for breaking down nutrients and storing vitamins and minerals that
are absorbed from food. The pancreas is responsible for producing mixes of
enzymes that are called pancreatic juice. This juice neutralizes acidic chyme
that enters the small intestines. The pancreatic juice is responsible for helping
the digestive system to digest proteins, fats, and carbohydrates. </span>
The plant will wilt because the concentration of water in saltwater is lower than the concentration of water in the plant itself (because it is a freshwater plant). Water will diffuse out of each individual cell and the cell will crenellate (or shrivel up) causing the plant to wilt.
The substance that is predominately absorbed in rain forests would be carbon dioxide, I believe. As many tropical trees are present and will uptake CO2 to synthesize glucose or sugar as a product of photosynthesis.
