Which of the Following Is the Best Description of Bioaccumulation

Endocrine disruptors mimic hormones that regulate critical biological processes. Tertiary consumer such as seals the greater the concentration of DDT in their body as a result of a process called biomagnification.

Bioaccumulation Bioconcentration And Biomagnification Life Science Lessons High School Environmental Science Biology Lesson Plans

Hearing and vision loss elevated blood pressure memory loss.

. DDT is very stable and as much as 50 of the original concentration can remain in the soil 15 years after the initial application. What essentially happens is that an organism absorbs the chemicals across their skin or otherwise takes. Food chains are important interrelations among the organisms in the ecosystems.

Endocrine disruptors do not biodegrade remaining toxic years after their release. Biomagnification refers to the increased concentration of a toxic chemical the higher an animal is on the food chain. Nervous system damage reproductive system damage kidney failure and impaired mental development.

It is a normal and essential process for the growth of organisms. Bioaccumulation occurs within a trophic level and is the increase in concentration of a substance in certain tissues of organisms bodies due to absorption from food and the environment. Bioaccumulate is in the form of toxins and other untreated stuff released into the water ecosystems.

Accumulation in living things can occur whenever metals are taken up and stored faster than they are metabolized or excreted Markich et al 2001. Bioaccumulation refers to the build-up of a toxic chemical in the body of a living organism. Which of the following best explains the potential health problems associated with endocrine disruptors.

Taking in chemicals faster than a living organism can break it down and use them. The first and major difference or points of comparison between these processes is that where on one hand bioaccumulation is the increase in the concentration of a substance inside an organism on the other hand biomagnification is the increase in the level as one. It usually occurs when an organism ingests a particular substance at a faster rate than it can metabolize or excrete.

Understanding the dynamic processes of bioaccumulation can have important ramifications in protecting. An increased concentration of a toxic chemical the higher an animal is on the food chain. Bioconcentration is defined as occurring when uptake from the water is greater than excretion.

Biosorption and bioaccumulation involve interactions and concentration of toxic metals or organic pollutants eg. The following is a list of some of the differences between both these processes. The higher an animal is on the food chain eg.

When an animal consumes food having DDT residue the DDT accumulates in the tissue of the animal by a process called bioaccumulation. Tertiary consumer such as seals the greater the concentration of DDT in their body as a result of a process called biomagnification. Nervous system damage immune system suppression heart kidney and lung damage.

The processes play an important role. Bioaccumulation refers to the accumulation of a toxic chemical in the tissue of a particular organism. The uptake of essential nutrients by plant roots.

Breaking down a chemical in the living. An increase in the concentration of a chemical in a biological organism over time compared to the chemicals concentration in the environment. The higher an animal is on the food chain eg.

An increase in the level as one moves higher in the food chain. Lead and fluoride bio. Which of the following is the best description of bioaccumulation.

An increase in the concentration of a substance inside an organism. Bioaccumulation refers to the increase in concentration of a pollutant in an organism. Accumulation of a toxic chemical in the tissue of a particular organism.

Bioaccumulation is the process by which toxins enter the food web by building up in individual organisms while biomagnification is the process by which toxins are passed from one trophic level to the next and thereby increase in concentration within a food web. All animals bioaccumulate vital nutrients daily such as vitamins trace minerals essential fats and amino acids. Many chemicals including dioxins polycyclic aromatic hydrocarbons PAHs polychlorinated biphenyls PCBs and organ metallic forms of metals bio-accumulate in animal fat Hill 1997 and are difficult to degrade.

The two causes of bioaccumulation are the amount of the chemical coming into the living organism faster than the organism. The key difference between bioaccumulation and biomagnification is that bioaccumulation refers to the build-up of a toxic chemical in the body of a living organism while biomagnification is the increase of the concentration of a toxic chemical when going along a food chain. Bioaccumulation is a process of the accumulate of the chemical constituent that doesnt decompose or that dont leave the digestive tracts of the animal and these keep on spreading with the passage of time.

Which of the following best describes why DDT is classified as a persistent organic pollutant. Bioaccumulation involves relative to the ambient value an increased concentration of a metal in a biological organism over time. Dyes in the biomass either living bioaccumulation or non-living biosorption.

The accumulation over time of a substance and especially a contaminant such as a pesticide or heavy metal in a living organism. Bioaccumulation is the build-up of chemicals inside of living organisms. Which of the following is one of the main causes of bioaccumulation.

Which of the following best describes the effect of lead on humans. Up to 24 cash back Not all bioaccumulation is harmful. Endocrine disruptors encompass a wide array of toxic pesticides.

Describes the entrance of a chemical into an organism. 2 Plantsanimals from which of. When an animal consumes food having DDT residue the DDT accumulates in the tissue of the animal by a process called bioaccumulation.

What concerns toxicologists is the bioaccumulation of certain substances to levels in the body that cause harm. The term bioaccumulation is used to refer to storage of a pollutant at levels higher than found in the environment.
