You have been studying a large lake ecosystem. You learn that toxins have been dumped into the water. You predict that the popul
Shtirlitz [24]

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.

olasank [31]

Answer:

Perma Dorji (PD) and Kesan Choden (KC) are children.

If the number of brother PD has is X, the number of sisters she has is 3X

If the number of brothers KC has is 3X, then the number of sisters she has is 3X-2

Explanation:

The total number of children (brothers and sisters) therefore are:

PDs siblings = 3X+X plus

KCs siblings = 3X2

= 3X+X +3X-2

=6x-2

Let's assume that X is 1, therefore the number of siblings equals

6(1)-2

= 4

Don't forget the PD and KC are also children.

Therefore, the total children in the family is equals to 6

Cheers!
