How does acid deposition impact aquatic environments? a. fish do not often die but they do become too full of toxins to be consumed by humans. b. aquatic environments become temporarily lifeless while new species of fish who can tolerate the acid deposition replenish the stock. c. fish that absorb the chemicals either die, become sterile or produce mutated offspring, and are too full of mercury to eat. d. aquatic environments are not directly impacted by acid deposition.

Your correct answer will be. C. fish that absorb the chemicals either die, become sterile or produce mutated offspring, and are too full of mercury to eat. Because, effects of the acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife.

hope this helps others that come to this question.

Acid deposition impacts aquatic environments because fish that absorb the chemicals either die become sterile. Also, they produce mutated offspring and are too full of mercury to eat.

Further Explanation:

Acid rain includes all types of precipitation with acidic content with a pH value of less than 7. These types of precipitation are harmful to aquatic animals and their infrastructure. Acid rain is the result of the reaction of Sulfur dioxide and Nitrogen oxide with water molecules present in the atmosphere.

Acid deposition is referred to all kinds of precipitation, smog, fog, and mist that have acidic content in it. Deposition can be dry or wet, but in all states, it is hazardous for the environment. The deposition generally has a pH value of less than four and can have pH value as a minimum of 1.5. Sulphuric acid and Nitric acid are two components generally found in the deposition. These acids clog the gills of fish and cause chronic stress. Also, the calcium level because of the acid is lowered and therefore, they are not able to produce the egg.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
