The concentration of DDT in fish is typically thousands of times greater than in seawater due to biomagnification, where DDT accumulates in organisms higher up the food chain. This accumulation occurs as fish consume smaller organisms with DDT residues, leading to higher concentrations in their tissues.

Explain biomagnification with the help of an example?
Biomagnification is the process where toxins become more concentrated as they move up the food chain. For example, a small fish may consume water contaminated with a toxic chemical. A larger fish then eats many of these small fish, accumulating a higher concentration of the toxin. Finally, when a human consumes the larger fish, they may be exposed to dangerous levels of the toxin due to biomagnification.
What is an example of osmosis in a living organism?
An example of osmosis in a living organism is the movement of water molecules into and out of red blood cells. When red blood cells are placed in a hypertonic solution (higher solute concentration), water will move out of the cells causing them to shrink. Conversely, when red blood cells are placed in a hypotonic solution (lower solute concentration), water will move into the cells causing them to swell.
What process is water moving out of the cell of a saltwater fish and into the ocean?
This process is called osmosis. Water moves from an area of low salt concentration (inside the fish cell) to an area of high salt concentration (ocean water) to balance the salt levels on both sides of the cell membrane.
Oak is to trout as tree is to?
fish.
How many cells do fish?
99 million
What are seawater fish?
A seawater fish is a fish that lives in the sea.
Is bluefish a freshwater animal or a seawater animal?

What do seawater fish look like?
There are thousands of species of fish and they all look different from one another in some way. Seawater fish look like fish as do freshwater fish.
Is a lionfish a seawater fish?
yes, it is a salt water fish
What is one way a saltwater fish controls the concentration of salt in its body?
Some fish balance water loss by drinking seawater and actively transporting chloride ions out through their skin and gills then the sodium ions follow passively out as well.
Is a goldfish a seawater freshwater or tropical fish?
Goldfish are freshwater, not saltwater.
Is oxygen soluble in seawater?
Fish and marine life are able to live because oxygen is soluble in water, including salt water/seawater.
Do tropical fish live in seawater?
There are millions of tropical fish in the tropical oceans. But they are all marine fish not freshwater fish. Freshwater tropicals can not live in saltwater.
Seawater that contains a substance that fishes breathe?
Seawater and fresh water contains oxygen that fish absorb using their gill. So the substance is oxygen.
Would seagull pee dissolve in seawater?
Urine does not dissolve, no. It's there in the seawater along with all the fish urine and seal urine and dolphin urine and pelican urine...
What substance does seawater contain which fish need for breathing?
Basically, gills and oxygen in the water. The fish will die if any one are missing.
What is it fish smell which cats are drawn to?
Cats are drawn to the fish smell because their sense of smell is different that ours. Their sense of smell is about 15 times greater than ours. They like the fish smell because they love to eat fish.
