What else can I help you with?
What is DDT and what does it have to do with bio magnification?
DDT is dichlorodiphenyltrichlorethane; biomagnification of DDT in some organisms is possible.
Why can biomagnification be a problem in ecosystems?
an increase in chemicals and pesticides like "DDT" can damage an ecosystem
What can people do to solve the problem of biomagnification?
we can solve the concentration of biological magnification if produce less DDT
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.
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.
What is an example of biomagnification?
Spraying a marsh to control mosquitoes will cause trace amounts of DDT to accumulate in the cells of microscopic aquatic organisms, the plankton, in the marsh. That is an example of Biomagnification.
Which organism had the most DDT in their bodies?
Birds of prey, such as peregrine falcons and bald eagles, had some of the highest levels of DDT in their bodies due to biomagnification through the food chain. This accumulation of DDT caused reproductive issues and population declines in these species. Efforts to ban DDT and other harmful pesticides have helped to reduce these impacts.
How many times greater ias the concentration of DDT in fish than seawater?
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.
Give one reason for the difference in the concentration of DDT in these organisms?
One reason for the difference in the concentration of DDT in these organisms could be the difference in their feeding habits. Organisms higher up in the food chain, such as birds that feed on fish, may accumulate higher concentrations of DDT over time due to the process of biomagnification.
Does DDT react with water?
DDT, or dichlorodiphenyltrichloroethane, is not particularly reactive with water. It is only slightly soluble in water and tends to persist in the environment for long periods of time. However, DDT can undergo hydrolysis in the presence of water under certain conditions.
Do chemical poisons in the bald eagles food cause eggs to crack before incubation is complete?
Yes. Farmers used a chemical called DDT on their crops as an insecticide This chemical would leak into the ground and pollute the water, eventually the fish in the water were poisoned and the eagles that ate the fish consumed large amounts of DDT due to biomagnification. Then when the eagles laid eggs, the DDT caused the shells off the eggs to be softer so when the mother eagle was incubating her eggs, they would be crushed.
Is DDT a parasite?
DDT is an insecticide.
