How does biomagnification work in the food chain?
Biomagnification occurs when toxic substances accumulate in organisms at higher levels of the food chain. As smaller organisms are eaten by larger ones, the toxins they have absorbed become more concentrated in the bodies of the predators. This can lead to harmful effects on top predators and other animals, including humans, who consume contaminated prey.
What happens to contaminants as you move up and down the ecological pyramid?
Contaminants tend to bioaccumulate, meaning they become more concentrated as you move up the ecological pyramid because organisms at higher trophic levels consume many lower-level organisms. Contaminants can also biomagnify, increasing in concentration along the food chain due to the cumulative effect of each organism consuming contaminated prey.
What are fomites?
Fomites are inanimate objects or surfaces that can become contaminated with infectious agents, such as bacteria or viruses, and contribute to the transmission of diseases. Common fomites include doorknobs, countertops, and shared electronic devices.
Is it possible for something nonliving to become something living?
No, something nonliving cannot become living. Living organisms are characterized by complex biological processes such as growth, reproduction, and metabolism. These processes require specific organic molecules and structures that nonliving things do not possess.
How does a housefly transmits disease?
Houseflies can transmit disease by landing on contaminated surfaces such as garbage or feces, picking up pathogens, and then transferring them to food or other surfaces through their body parts or feces. When people come into contact with these contaminated surfaces, they can unknowingly ingest the pathogens and become sick.
What happens to living things when they eat organisms that have been exposed to DDT?
These living things become contaminated with DDT.
Is it possible for water to be radioactive?
Yes, it is possible for water to become radioactive if it comes into contact with radioactive materials or is contaminated by radioactive substances.
What does biomagnification do to the food chain?
If a producer or low level member of the food web somehow takes in a toxin, the toxin remains in that organism. The organism that consumes the one that has become contaminated will consume several of those organisms, which are potentially all contaminated. There fore, the organism that has consumed contaminated organisms will get a stronger dosage of the toxin, and the cycle continues as the toxin moves up the food web.
How could eggs become contaminated?
They can be contaminated by the chicken if the chicken has pathogens.
Does the geiger muller tube become radioactive?
no. as with anything in a contaminated area its surfacemay become contaminated, but this can and should be washed off.
What happens to populations when water supplies become contaminated?
Everyone will become sick.
What organic foods are sometimes bad for you?
Like any foods, organically grown foods can become contaminated with unhealthy organisms, which means they would be bad for you. Unless that happems. organic foods are healthy.
When foods are contaminated and not handled correctly people can become sick Which of the following is most likely to contaminate foods?
I think all of these can become contaminated dy disease
How might food utensils become contaminated?
Food utensils become contaminated when pathogens are transferred to its surface. This will happen when the utensils are not washed thoroughly, or someone with dirty hands touches them.
How does groundwater become contaminated?
Water becomes contaminated by people throwing trash on the ground and it ends up in the ground water.
If you become contaminated with chemical agents decontaminate by?
24 hours
How can a indicator become contaminated?
An indicator can become contaminated through exposure to environmental sources, improper handling, or contact with contaminated surfaces or materials. This can include inadequate sterilization practices, cross-contamination from other substances or samples, or exposure to air, water, or surfaces that contain contaminants.
