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.
One property that makes DDT hazardous over time is that DDT is?
DDT is used as an insecticide which kills on contact. It is extremely harmful and was banned in United States since 1972.

This led to ban in DDT in many countries.
What are the disadvantages of using DDT?
DDT is harmful to the environment and can persist in the soil and water for a long time. It can also bioaccumulate in the food chain, leading to negative health effects in organisms at higher trophic levels, including humans. Overuse of DDT has also contributed to the development of DDT-resistant insects.
How is algae harmful to the ecosystem?
Algae can be harmful to the ecosystem by causing algal blooms, which deplete oxygen levels in waterways and harm aquatic life. These blooms can also release toxins that are harmful to other organisms in the ecosystem. Additionally, when algae die and decompose, they can further reduce oxygen levels in the water, leading to dead zones where marine life cannot survive.
