Aristo was riding in a car and noticed a pond that was covered in algal blooms. which of these other features in the landscape could be the reason for the high levels of phosphorus?

"Cow pasture" is the other feature in the landscape among the choices given in the question that could be the reason for the high levels of phosphorus. The correct option among all the options that are given in the question is the second option.

The other options are incorrect because:

Cars produce carbon monoxide emissions, not phosphorus

Solar Panels don't produce waste from use

Forest ecosystems efficiently cycle nutrients

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.
