What is the MOST well known negative side effect of using DDT?
The most well-known negative side effect of using DDT is its harmful impact on the environment and wildlife. DDT is known to bioaccumulate in the food chain, leading to the poisoning of birds and other animals.
What scientists were making the discovery of DDT around 1940?
Paul Hermann Muller discovered the insecticide effect of DDT in 1939 but the compound is known from 1874.
What kind of soluble is DDT?
DDT is a fat-soluble compound, meaning it dissolves in fats and oils but is not water-soluble. This property allows DDT to accumulate in the fatty tissues of organisms, leading to potential bioaccumulation and biomagnification in the food chain.
What organisms have the most pesticides?
The organisms at thetop of the food chain will contain the most DDT. These are the top carnivores (or humans if we are in the food chain).DDT builds up in food chains for several reasons:1) It is a persistent pesticide IE: it is difficult for any organisms to break it down, it is non-biodegradable.2) It is soluble in fat, so it enters the fat storage tissue (adipose tissue) and stays there.3) Organisms higher in the food chain consume DDT every time they feed on organisms lower down in the food chain, if they are contaminated with DDT.4) The biomass at each level in a food chain gets less, so the concentration of DDT will increase.The increase in concentration of pesticides in a food chain is called bio-magnification.Additional Information: Seals, Predatory Fish, Bears, Predatory Birds, Bats.
What is meaning by bioaccumulation and how does it apply to DDT?
Bioaccumulation refers to the accumulation of a substance in an organism's tissues over time. In the case of DDT, a pesticide used in the past, it bioaccumulates in the fatty tissues of organisms as it moves up the food chain. This can lead to higher concentrations of DDT in organisms higher up the food chain, posing potential risks to those predators.
How do food chains effect food chains?
they don't effect the food chain there are still crabs right then how do we effect the food chain.
Why is DDT a persistent chemical?
DDT is a persistent chemical because it is resistant to degradation by natural processes like sunlight, heat, and microorganisms. This allows it to remain in the environment for a long time, accumulating in organisms and biomagnifying through food chains.
What is the MOST well known negative side effect of using DDT?
The most well-known negative side effect of using DDT is its harmful impact on the environment and wildlife. DDT is known to bioaccumulate in the food chain, leading to the poisoning of birds and other animals.
As ddt moves up the trophic levels in food chains its concentration?
increases. This is known as biomagnification, where organisms higher up in the food chain accumulate higher levels of DDT due to consuming prey that have ingested or absorbed the chemical. This can lead to harmful effects on top predators due to the higher concentrations of DDT in their bodies.
How did DDT enter the food chain?
DDT entered the food chain because it was in the water of the fish that bald eagles ate.
What does DDT mean in global warming?
DDT (dichlorodiphenyltrichloroethane) is a pesticide. It has nothing to do with global warming. It was however used as an example of the bio-accumulation of chemicals in the ecosystem which may harm animals, fish and birds. DDT was used as an example of these problems in Rachael Carson's book "Silent Spring"
How does ddt build up in food chains?
Because energy is lost as you move up a food chain, more organisms must be consumed in each successive level to maintain the level of energy necessary to biological processes. For example, say a grasshopper has to eat one blade of grass in order to gain the requisite energy and there are 10 drops of DDT on each blade of grass. This means each grasshopper has 10 drops of DDT. Now a bird has to eat 10 grasshoppers in order to obtain the right amount of energy so each bird now has 100 drops of DDT, and so on as you proceed up the food chain.
What is the relationship between biological magnification and the reduction of the bald eagle population by pesticide DDT?
because DDT accumulates in fatty tissue, DDT concentrations increase as this chemical moves up in the food chain because at the top of the food chain, DDT concentration has increased almost 10 million times
What scientists were making the discovery of DDT around 1940?
Paul Hermann Muller discovered the insecticide effect of DDT in 1939 but the compound is known from 1874.
Why does osprey contain large amounts of DDT?
DDT concentration is higher in ospreys because they eat the animals that have concentrations of DDT in it. As DDT passes up the food chain it gets more and more concentrated. THis is due to the 10% rule. wiki it.
How can you reduce the bad effect of DDT?
Put a piece of bacon in your butt and eat it.
What is a model that shows how food chains are connected?
They are called food chains.
