Answer:

The concentration of DDT in-ring seals is higher than the concentration in the arctic cod because the concentration of DDT increases in the higher food chain due to biomagnification.

When organisms at lower food chain bioaccumulate chemicals like DDT get eaten by organisms at higher food chain then the concentration of DDT increases called biomagnification.

Arctic cod are the small fish which eats small copepods, then arctic cod is eaten by big fish and then these big fishes are eaten by ring seals. Therefore ring seals have a higher concentration of DDT than arctic cods.

Flow chart of biomagnification :

Tiny algae→copepod→arctic cod→bigger char fish→ring seals

as we go higher in the food chain, the accumulation of pesticides increases, because ring seals are in higher rank than the Arctic cod, that's why there is much higher concentration of DDT is present in ring seals.

Thiobacillus denitrificans is a species of bacteria that obtains its energy from carbon dioxide and inorganic compounds such as
tensa zangetsu [6.8K]

Answer:

The correct answer would be - nitrficiation, denitrification, nitrogen fixation, and decomposition.

Explanation:

Thiobacillus denitrification is a facultative, obligate chemolithoautotrophic anaerobic bacterium that is well known for its ability to couple the oxidation of inorganic sulfur-based compounds to denitrification.

The name of the bacterium is derived from its function or the metabolic ability as it performs denitrification on thio (sulfur) based inorganic compounds by the process of oxidation. This process helps in bioremediate groundwater by these processes of nitrogen fixation by oxidation of inorganic compounds of sulfur.

Thus, the correct answer is - nitrification, denitrification, nitrogen fixation, and decomposition.

You observed many sand hill cranes on your walk. Two sand hill cranes flapped their wings and hopped up and down when you walked
Anarel [89]

Answer:

This question lacks options, the options are:

A) symbiosis

B) ecosystem

C) community

D) population

E) biosphere

The answer is D) Population

Explanation:

Living organisms in an ecosystem are usually found in numbers living together in a given area. This is termed POPULATION in ecology. A population refers to the group of living organisms that belongs to the same species living together in the same habitat and have the ability to interbreed i.e. mate and reproduce with one another.

This is the case in this question where many sandhill cranes (large flying birds) were observed in a particular area, which represented their habitat. Asides the group of sandhill cranes living together, they were also observed to be interbreeding. This was evident in the observation of two sandhill cranes hopping up and down around their bright orange baby. This shows that members of the population are capable of mating and reproducing fertile offsprings.

This observation completes what a POPULATION is all about, hence, a population was observed.
