Explain what happens to environmental poisons as you move up the food chain?
They accumulate as you move up the food chain because,They travel from organism to organism.For example,it may enter a food chain when it's absorbed by a plankton,and the pollutant is passed on to which ever organism eats the plankton,and it keeps on going on. By The Way,the person who just answered this is in gr.7 my name is ar$h!
When poisons build up in higher levels in a food chain what terms is used?

Explain why animals at the top of the food chain are particulary at risk from poisons in the environment?
Mainly the buck stops there

How do toxins build up in food chain?
The toxins which are built up in food chain are the toxins which consist of heavy metals such as led, cadmium, mercury. since most of the agrochemicals contain these heavy metals, they tend to accumulate in the food chain. Once a heavy metal get into a body of an animal, it will be deposited in fat tissues thus it cannot be eliminated therefore with increase intake of those heavy metals ,more and more heavy metals accumulate in the food chain. Apart from those toxins food cantain naturally occurring toxins as well.
How does the DDT originnaly enter the food chain?
DDT originally enters the food chain through runoff from agricultural fields or from direct application to crops. It can then be absorbed by plants and accumulate in the tissues of animals that eat these plants. This process is known as bioaccumulation.
Why animals at the top of a food chain are particularly at risk from poison in the environment?
This is biological magnification; the concentration of poison in the environment gets higher and higher as it goes up the food chain. The poisons are kept in the bodies of the animals that eat them. They are not broken down or eliminated. So a predator that is higher up the chain gets a lot of the poison from its food. -Shawney M.
