Identify the part of the digestive tract that removes water and has a lot of bacteria living in it.

The part of the digestive tract that removes water and has a lot of bacteria living in it is the large intestine. Here's a step-by-step explanation:

1. The digestive tract is a series of organs that food passes through when it's being digested. It starts at the mouth and ends at the anus.

2. After food is chewed and swallowed, it travels down the esophagus and into the stomach, where it's broken down by stomach acid.

3. The partially digested food then moves into the small intestine, where most of the nutrients are absorbed.

4. After that, the remaining undigested food material and water move into the large intestine, also known as the colon.

5. The large intestine is responsible for absorbing most of the remaining water, electrolytes, and vitamins produced by enteric bacteria.

6. The large intestine is also home to a large number of bacteria, which help break down the remaining food material.

7. Finally, the waste material is passed into the rectum and then expelled from the body through the anus.

So, the part of the digestive tract that removes water and has a lot of bacteria living in it is the large intestine.
