which environmental change caused all populations of the biotics factors (algae, mosquito larvae, minnow, trout, and heron) to increase?\n○ increase in runoff\n○ drought in the area\n○ pollution from the factory\n○ introduction of a non - native species

Answer

Brief Explanations:

An increase in runoff can bring more nutrients and water, which is beneficial for the growth and reproduction of algae, mosquito larvae, minnow, trout, and heron. Drought reduces water - availability and harms populations. Factory pollution is harmful. Introduction of a non - native species can disrupt the ecosystem and may not lead to an increase in all these populations.

Answer:

increase in runoff
