When fertilizer runs off into streams and lakes, what increases in the water? select all that apply.
a. organisms like fish
b. the number of algae
c. the amount of oxygen
d. the amount of toxic chemicals

D, B

Algae will increase since the fertilizer has chemicals that will set with the water.

Toxic chemicals will rise since the fertilizer was made in a factory.

Not sure about fish tho because the lake can refill it's life after a while and the chemicals can work as a counter measure.
