At which level is the concentration of chemicals highest in a food chain and why?

An animal higher up on the food chain tends to have a greater concentration of chemicals because of what it eats. Even though there might be very little concentration of chemicals in the tissues of an organism at the bottom level of the food chain, the concentration of chemicals builds up as you go up the food chain.

At which level of the food chain are the highest levels of harmful chemicals?

At each trophic level of the food chain, the toxins remain in the tissues of the animals - so the concentration of toxin becomes most concentrated in the body tissues of the animals at the top of the food chain.

Why is there a higher concentration of toxins at the top of the food chain?

Organisms at the top have a higher tissue concentration of toxins and pollutants than lower levels. The concentration system is due to persistence of the toxins, food chain energetics, and low rate of internal degradation or excretion of the substance. Trophic level I represents the primary producers.

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

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

What is usually the highest level of a food chain?

species at the top of the food chain, with no predators of its own. Also called an alpha predator or apex predator. one of three positions on the food chain: autotrophs (first), herbivores (second), and carnivores and omnivores (third).

Chemical contaminants in the food chain

Does the top of the food chain has the most energy?

Many of the organisms linked in the food chain/web do not interact at all. 2) The top of the food chain has the most energy because it accumulates up the chain. Organisms transfer energy to the surroundings in daily activities such as movement, generating body heat, reproduction, and excretion.

Which species occupies the highest trophic level and why?

The highest trophic level is the apex predators. Primary consumers are carnivores that survive on secondary consumers (herbivores).

In which trophic level biomagnification is highest?

So the correct answer is 'secondary consumers'.

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.

Which organism in the food web will contain the highest concentration of chemical pollutants?

Answer. This is biomagnification, and it means that higher-level predators-fish, birds, and marine mammals-build up greater and more dangerous amounts of toxic materials than animals lower on the food chain.

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.

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

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 of the following will have the maximum concentration of harmful chemicals in its body?

Grass Grasshopper Frog Snake Eagle The organism which occurs at the highest trophic level in the food chain will have the maximum concentration of harrnful chemicals in its body. since, eagle occurs atthe highest trophic level, therefore, it will have the maximum concentration of harrnful chemicals in its body.

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 is biological magnification at which trophic level in a food chain this magnification is maximum give reason to your answer?

The levels of biological magnification is different at different levels of the ecosystem. It will be increases with each successive level. It is maximum at highest tropic levels and minimum at lowest tropic levels. For example, it is higest in humans and lowest in autrophs like plants.

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 are higher trophic levels?

The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and typically finish with apex predators at level 4 or 5.

What is the highest trophic level of the ecological pyramid?

Ecological pyramids begin with producers on the bottom (such as plants) and proceed through the various trophic levels (such as herbivores that eat plants, then carnivores that eat flesh, then omnivores that eat both plants and flesh, and so on). The highest level is the top of the food chain.

What do you think is the reason as the trophic level goes higher the size of the organism becomes larger but the number of individuals becomes lesser?

With less energy at higher trophic levels, there are usually fewer organisms as well. Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass.

Which level has the most energy?

Since the source of energy is the sun, the trophic level representing producers (plants) contains the most energy.

Which level of consumers has the most energy?

Answer and Explanation: The first trophic level of the food chain has the most energy.

Why is there less energy at the top of the food chain than at the bottom?

Most of the food energy that enters a trophic level is "lost" as heat when it is used by organisms to power the normal activities of life. Thus, the higher the trophic level on the pyramid, the lower the amount of available energy. Encyclopædia Britannica, Inc.

Which of the following in the food chain will have maximum concentration of harmful chemicals in its body small fish?

The correct answer is Kingfisher. The organism which occurs at the highest trophic level in the food chain will have the maximum concentration of harmful chemicals in its body. Since Kingfisher occurs at the highest trophic level, therefore, it will have the maximum concentration of harmful chemicals in its body.

Which of the following will have the maximum concentration of harmful chemicals in its body give reason peacock Frog grass snake Grasshopper?

Answer: Peacock, Frog, Snake, Grasshopper. In this food chain, since peacock occurs at the highest trophic level (on the extreme right side), therefore, peacock will have the maximum concentration of harmful chemicals in its body.

Who would have received the maximum and minimum chemical energy through the food chain respectively?

1 Answer. Grasshopper will have the minimum and peacock will have the maximum concentration of chemicals in their body.
