Answer:
See below, please.
Explanation:
The biological level of seal is higher than fish. The amount of microplastics in the body of fish is X mol. As a seal eats Y fishes one day, so the amount of microplastics in the body of the seal is YX mol.
Seals are the consumers that feed on the fish for food. The concentration of the microplastics in a seal’s body will be higher than the fishes due to a process called bioaccumulation or biomagnification.
What are bioaccumulation and biomagnification?
Bioaccumulation is the chemical accumulation in higher concentrations in an organism over a period of time where the rate of excretion is slower than the intake.
Biomagnification, on the other hand, is the process where the concentration of the chemicals in the organism at the higher level of the pyramid is more than at lower levels.
The seal is at a higher ecological level in the food pyramid and feeds on fish. The concentration of the microplastics increases in their body as they feed on more fish and are at a higher trophic level.
Therefore, the concentration of microplastics increases in Seals due to bioaccumulation and biomagnification.
