How can the presence of one species benefit another in the same ecosystem
tekilochka [14]

Answer:

The different species present in an ecosystem make the ecosystem balanced.  The species of an ecosystem interact with one another in one form or the other. For example, the presence of a plant species will provide food for the abundant types of herbivores present in an ecosystem. A predator might feed on many types of preys. Hence, the presence of different preys will reduce the chances of a species from becoming wiped out from the ecosystem. Hence, all the organisms in an ecosystem are dependent on another in some way or the other.

Three effects of constipation​
algol13

1. Infections

If you end up being constipated, you are probably having trouble passing a stool. If the stool has become dry and hard from lack of moisture, it could make having a bowel movement painful. When the rectum is stretched out to accommodate the painful stool, the rectum could stay open resulting in rectal prolapse. This could lead to an infection.

 

2. Bad breath

One unusual side effect is bad breath. You may wonder how a condition that is occurring at one end of your body could affect the complete opposite end of your body, but it can. What happens is the gasses and toxic waste that are building up because you are constipated rises up and as it goes throughout the body and it usually ends up in your mouth.

3. Lowered ratio of healthy bacteria

Healthy bacteria in your body is called flora. The purpose of flora is to help with the production of vitamins and helps with your immune system. When you are constipated the amount of flora in your intestine is reduced putting you at risk for illness and infection.

Extra Options

4. Colon cancer

The colon is meant to store a couple of pounds of stools. If you become constipated, there is a buildup of stools and puts the colon at risk for ripping. When the colon becomes strained because it is overloaded, it strains the inner membrane. Ruptures and possible infections occur and it could lead to colon cancer.

 

5. Increased toxins

Your skin will show on the outside what your body is going through on the inside. If you become constipated, you will suffer an excess of toxins in your body. The skin, your largest organ, has to work overtime to get rid of these toxins. If your skin looks less than glowing you need to address the issues that are going on inside of your body before you start looking for a new facial cream.
