What scientific studies support the decision to ban DDT?
Eagle populations recovered after the ban on DDT.
What kind of gene mutation is most disruptive to an organism?

How does an animal living hundreds of kilometers from an area sprayed with DDT might get DDT in its body?
Many animals migrate at specific times of the year. An organism with DDT in its tissues may migrate a distance from the area it was sprayed; it may be consumed by a carnivore that would store a higher concentration of DDT in its body tissue. Migrating birds can carry DDT in their bodies even though they inhabit and can be consumed in an ecosystem that is distant from the one that is sprayed. The peregrine falcon is a species of bird found to have high concentrations of DDT in its body. The habitat of the falcon is quite broad, ranging from the North American boreal forest to areas of the southern United States. Falcon prey on organisms in areas where use of DDT is still prevalent, then migrate to areas where the use of DDT has been banned.

Why is DDT considered to be harmful?
When DDT gets into the plasma membrane of your skin, nerve impulses (signals) no longer fire when they are supposed to.Nerve impulse tell the muscles when to contract and relax. Thus, when an organism is poisoned with DDT, it dies by either convulsions or paralysis
How does DDT get into the bodies of zooplankton?
Herbivores (like deer) eat the plants that it gets spread on. We'll say the plants have 1 piece of DDT. Since each deer eats LOTS of individual plants (we'll say leaves), the DDT in the deer will be more than the leaves had. We'll say this deer ate 100 leaves in one day, now it has 100 pieces of DDT in it. Then a wolf comes along and kills the deer and eats all the deer. Now the wolf has 100 pieces of DDT in it. The wolf kills ANOTHER deer the next day and eats it, and now this wolf has 200 pieces of DDT in it. So on and so on. So the MORE DDT you have in an organism's system, the more toxic it is. We call this bioamplification. Each food level it increases GREATLY in the fatty tissues.
What is the relationship between the trophic level of an organism and the concentration of DDT in its body?
If an animal on a high trophic level eats other organisms on a lower trophic level effected by DDT, the animals level will be affected.
What does ddt kill?
With a high enough concentration, any organism with a nervous system. It attacks nerve cells, leaving an organism to die of paralysis (inability to move) or convulsions.
Why is DDT controversial?
Very dangerous. causes kidney/liver disease and kidney/liver cancer and leads up to death. was banned in 1972 by the US Secretary of agriculture, Richard Milhous Nixon and the World Health Orginization. Cased by inhaling the chemical.
Do chemical compounds remain in the organism permanently?
Some do and some do not. Water-soluble compounds can pass out of an organism fairl easily. Some compounds, such as DDT, however, do not leave the body.

How long does DDT last?
DDT is a persistent chemical that can remain in the environment for a long time. It has a half-life of around 2 to 15 years in soil and can remain in water bodies for several years. However, the use of DDT has been phased out in many countries due to its harmful effects on the environment and human health.
Organism with porous bodies belong to what phylum?
Organisms with porous bodies belong to the phylum Porifera, which includes sponges. Porifera are multicellular, aquatic organisms that lack tissues and organs. The porous nature of their bodies allows water to flow through and for filter feeding.
