Many nutrients are absorbed actively.So this energy is produced by mitochondria.
Small intestine has lots and lots of villi and microvilli for absorption, large intestine absorbs water and it has lots and lots of goblet cells that produce mucus so it's easier to remove waste (aka poop)
If a cell has a relatively large number of, say, mitochondria (sites of respiration), than we know that it needs to release a lot of energy. This applies to the muscles, which have many mitochondria in order for them to contract. This helps us move. Cells where active transport occurs, such as the kidneys and small intestine, also need lots of mitochondria to give off the energy that is necessary for this to take place. You won't find as many mitochondria in a skin cell, because these don't need to carry out respiration.
every animal has mitochondria in it. The one with the most would probably be an animal that eats lots of grass and needs lots of energy like tigers zebras or gazelles
Metabollically very active cells.As examples,cardiac,muscle cells.

1)Villi and micro villi increase the surface area for the absorption of digested food. 2)Epithelial cells lining the intestine have a high volume density of mitochondria, meaning lots of energy for the active uptake of digested food. :)
your esophagus and small intestine are attached to your stomach.
No. The anus only serves as an exit for waste. There are often large obstructions in the large intestine, in addition to impassable sphincters separating the large and small intestine and the small intestine and the stomach, and the presence of lots of liquids in the small intestine and the stomach. You can breath through your mouth, your nose, or (in the case of some smokers) a small recessed hole in the neck directly connected to the windpipe.

Muscle cells have lots of mitochondria. Mitochondria is known as a "powerhouse" of the cell. In the inner membrane matrix of the mitochondria there are ATP synthases that generate ATP energy.
Mitochondria give energy to cell.It stores about 40% of glucose' energy in ATP.
Lots.

The process of digestion is mainly in the stomach but lots of things are also digested in the small intestine e.g. maltose into glucose (enzyme used is maltase), protein into amino acids (protease is the enzyme) and lipids into glycerol and fatty acids (lipase is the enzyme) When these have been broken down they are absorbed through the lining of the small intestine where they are absorbed into the blood (absorbtion) and used as raw materials for growth and tissue repair (assimilation). So the answer is the small intestine Hope that helped =)
Lots of Mitochondria to respire A tail to swim
