Salt Levels: Why High Molarity Can't Support Marine Life

In summary, the conversation discusses the impact of high salt levels on marine life. The process of osmosis is explained, which can cause cells in a fish's body to either expand or shrink. While most fish and other macrobiotics cannot survive in high salinity environments, there are some organisms that have adapted to life under extreme salt conditions.

Bodies with high molarity of salt (salt levels) cannot sustain marine life? but why? please help. thanks!

Osmosis: unless the concentration is the same as in your (the fish's) body, osmosis will occur and the cells in your (the fish's) body will either blow up like balloons until they explode or shrivel up.

Your question is somewhat dependent on what you mean by "marine life", if you are referring to fish and other macrobiotics then yes they typically don't do well in environments with salinity into the +2M range. However search the terms halophile (translated: salt-loving) or halotolerant and you will see that numerous lifeforms have adapted to life under such extreme conditions. You should also be able to find out how these organisms beat the process of osmolysis brought up by russ_watters.
 

1. What is high molarity and how does it affect marine life?

High molarity refers to a high concentration of salt in a solution. This can be harmful to marine life because it can disrupt the osmotic balance of organisms, making it difficult for them to regulate their internal salt levels.

2. How does high salt levels in water affect marine ecosystems?

High salt levels can have a negative impact on marine ecosystems by causing dehydration and stress in organisms. It can also alter the composition of the water, making it more difficult for certain species to survive.

3. What are some signs that salt levels in water are too high for marine life?

Some signs of high salt levels in water include changes in the behavior and appearance of marine organisms, such as reduced activity and discoloration. In extreme cases, high salt levels can lead to mass die-offs in certain species.

4. How do scientists measure salt levels in water?

Scientists use a device called a salinometer to measure the salinity of water, which is a measure of the concentration of salt. This device works by measuring the electrical conductivity of the water, as salt is a good conductor of electricity.

5. Can anything be done to lower high salt levels in the ocean?

There are some steps that can be taken to lower high salt levels in the ocean, such as diluting the water with fresh water or using certain types of filtration systems. However, it is important to also address the root causes of high salt levels, such as pollution and climate change, to prevent further harm to marine life.
