The correct answer is predatory birds.
The flowing of toxic chemicals and heavy metals into the water body when the agricultural, industrial, and human wastes run off or are discharged intentionally into the water body is known as biomagnification. These pollutants result in genetic mutations, disease, reproductive difficulties, birth defects, death, and behavioral modifications in various marine species.
However, the extremity of the destruction varies significantly among the species. In various circumstances, the animals close to the top of the food chain are most influenced by the procedure of biomagnification.
Several of the harmful toxins get settle at the lower level in a water body and are then consumed by the species, which feed or live on the bottom dwellers. As these constituents are not digested, they gathered inside the bodies of the species, which consumes them.
It signifies that the higher level predators, like fish, birds, or marine mammals accumulate more harmful concentrations of toxic substances in comparison to the animals lower on the food chain. Thus, in the given case, the more concentrated amount of toxins would be found in the predatory birds.
In a large lake ecosystem, the population with the highest concentration of the toxin would likely be the zooplankton. This is because they consume contaminated algae, transferring and concentrating the toxins in their bodies.
The population with the highest concentration of the toxin in a large lake ecosystem would likely be the zooplankton. Zooplankton are primary consumers that feed on algae, which is where the toxin would accumulate. As they consume contaminated algae, the toxin would be transferred and concentrated in their bodies.
Although other organisms like ducks, predatory birds, and small fish may also be affected by the toxin, the highest concentration is expected in the zooplankton because they have a direct dependence on the algae.
This scenario is applicable to a Biology class in High School, where students learn about ecological interactions and trophic levels.

Answer:
Most tissues of the body grow by increasing their cell number, but this growth is highly regulated to maintain a balance between different tissues. In adults most cell division is involved in tissue renewal rather than growth, many types of cells undergoing continuous replacement.
The multiplying of cells helps the body to either fight diseases or to keep up with the growth of adolescents all the way to adults.

Every living thing is made up of cells. If cells did not exist, there would be no life.
