The environmental change that would likely cause all populations of the biotic factors (algae, mosquito larvae, minnow, trout, and heron) to increase is **an increase in runoff**.
Increased runoff can lead to higher nutrient levels in water bodies, which can promote the growth of algae (eutrophication). As the algae population increases, it provides more food for mosquito larvae, which can also multiply in response. With more food available (in the form of algae and mosquito larvae), populations of minnows and trout may increase as they find more resources to sustain their populations. Furthermore, an increase in the populations of fish can lead to a rise in the heron population as they have more prey available to them.
The other options, such as drought, pollution from the factory, and introduction of a non-native species, would likely have negative impacts on these populations or would not uniformly cause increases across all these groups.
