Describe, in three or four steps, how toxins get more concentrated in organisms going up the food chain

Biology
1 answer:
Firdavs [7]3 years ago
7 0

Explanation:

Small amounts of toxic substances - often pesticides or pollution from human activity - are absorbed by plants.

These plants are eaten by primary consumers in low concentrations.

The toxin cannot be excreted so when the primary consumers are eaten by secondary consumers all the toxin is absorbed by the secondary consumers.

This repeats as secondary consumers are eaten by higher level consumers.

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.

Lesechka [4]

Answer:

Cross the flies with the flies from another population

Explanation:

Inbreeding is the mating between the closely related individuals of a population. Inbreeding reduces the viability of the progeny over a generation since it increases homozygosity. When the flies of a small population interbred over generations, the increased homozygosity reduces the viability of the flies. To counteract it, one should mate these flies with the flies from another population. This would increase heterozygosity and thereby would increase the survival and fitness of the progeny.
