What is the increased concentration of a toxic chemical The higher the trophic level is?

Biomagnification refers to an increase in the concentration of the toxicant at successive trophic levels.

What describes the increased concentration of toxic chemicals in the higher trophic levels?

The term food web biomagnification is used to describe trophic enrichment of contaminants within food webs and refers to the progressive increase in chemical concentrations with increasing animal trophic status.

Which trophic level has the highest concentration of toxins?

the last trophic level of a food chain has the highest concentration of toxic substances.

Which is the increasing concentration of toxic substances in organisms as trophic levels increase in a food chain or food web?

Biomagnification refers to the increased concentration of a toxic chemical the higher an animal is on the food chain.

What describes the increased concentration of toxic chemicals in the higher trophic levels quizlet?

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.

Increase in concentration of toxic substances at successive trophic levels due to their accumulation

Is the increased concentration of a chemical at each higher level of a food chain quizlet?

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.

What describes the concentration of toxic chemicals in the food chain?

Biomagnification, also known as bioamplification or biological magnification, is any concentration of a toxin, such as pesticides, in the tissues of tolerant organisms at successively higher levels in a food chain.

Why does the concentration of toxic substances increase from a lower to a higher trophic level?

Biomagnification increases the concentration of toxic substances in organisms at higher trophic levels. DDT is an example of a substance that biomagnifies; birds accumulate sufficient amounts of DDT from eating fish to cause adverse effects on bird populations.

What is the increasing concentration of persistent toxic substances in organisms at each successive trophic level?

Biomagnification is the increasing concentration of persistent, toxic substances in organisms at each successive trophic level.

Why does concentration of harmful chemicals increase whereas energy level decrease from lower to higher trophic level in a food chain?

Answer. The harmful chemicals mainly consists of pesticides and fertilizers ..as pesticides and fertilizers are non biodegradable they do not get digested or decomposed in any organism due to which it gets accumulated and passed on to higher trophic level.

In which trophic level biomagnification is highest?

So the correct answer is 'secondary consumers'.

Why do toxins accumulate at such high levels?

Why do toxins accumulate at such high levels in carnivores? The biomass at any given trophic level is accumulated from a much larger toxin-containing biomass ingested from the level below. Because they are at the top of the energy pyramid they eat the most food and so accumulate the most toxins.

Which of the following is an example of pollutants whose concentration increases in each trophic level?

An example is DDT whose concentration increases at each trophic level.

What is meant by biomagnification?

: the process by which a compound (such as a pollutant or pesticide) increases its concentration in the tissues of organisms as it travels up the food chain In a process known as biomagnification, fish accumulate mercury more rapidly than they excrete it, and every fish up the aquatic food chain contains more than the ...

Why does concentration increase biomagnification?

When predatory animals consume their prey they also consume all of the toxic chemicals within said prey. When these toxins aren't easily excreted they build up in the animal's system through bioaccumulation. Therefore, when the food chain progresses, concentrations increase or magnify.

How does biomagnification increase?

Disruption of Food Chain

The chemicals and toxins which are released into the water bodies disrupt the food chain. The small organisms absorb the toxins which are eaten up by larger animals. These toxins, thus, get accumulated in the higher level of organisms.

When the concentration of certain non biodegradable chemicals increases at each successive trophic level it is known as?

The increase in concentration of a non-biodegradable substances in successive trophic levels is called biological magnification. The increase in concentration of a non biodegradable substances in successive trophic levels is called biological magnification.

What is biomagnification and bioaccumulation?

Bioaccumulation takes place in a single organism over the span of its life, resulting in a higher concentration in older individuals. Biomagnification takes place as chemicals transfer from lower trophic levels to higher trophic levels within a food web, resulting in a higher concentration in apex predators.

What ecological term is used to describe the increase in the concentration of a toxicant at successive trophic levels?

Biomagnification refers to an increase in the concentration of the toxicant at successive trophic levels.

Is the increasing concentration of toxic substances?

Detailed Solution. The increasing concentration of toxic chemicals at successively higher levels in a food chain is known as biomagnification.

What occurs when toxic burden of a large number of organisms at a lower trophic level is accumulated and concentrated by a predator in a higher trophic level?

Biomagnification - effects of toxins are magnified (increase) in the environment through food chains. It occurs when the toxic burden of a large number of organism at a lower trophic level is accumulated and concentrated by a predator in a higher trophic level.

What happens to toxins as you go up the food chain?

considered the major mechanism for contaminant accumulation in organisms higher up in the food web”; in other words, toxins ingested by single-celled organisms are subsequently eaten by larger and larger organisms, compounding the amount of toxin at each level in comparison to the amount of tainted food eaten.

Which trophic level in the given pyramid has lowest and highest concentration of chemical pollutants?

Answer. Top Carnivore or we can say secondary consumer has the highest concentration of toxic substances in a food chain...

What part of the food chain is most affected by toxins?

Bioaccumulation occurs when toxins build up - or accumulate - in a food chain. The animals at the top of the food chain are affected most severely. This is what happens: Small amounts of toxic substances - often pesticides or pollution from human activity - are absorbed by plants.

What is organism trophic level?

Trophic level is defined as the position of an organism in the food chain and ranges from a value of 1 for primary producers to 5 for marine mammals and humans. The method to determine the trophic level of a consumer is to add one level to the mean trophic level of its prey.
