Severe acid rain caused by factory emissions can erode the leaves of plants. which statement best explains why this would harm the plant life? a. water needed for growth would not be able to be taken up from the soil. b. insects needed for pollination would not be attracted to the plants. c. sunlight needed for energy would not be able to be absorbed. d. nitrogen compounds needed for growth would not be available.

.  

Sunlight needed for energy would not be able to be absorbed.

Explanation:

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.

explanation:

the median of the data is 4.5.
