After fertilizer runoff enters a pond, algae cover the surface, aquatic insects decline, and dissolved oxygen falls. Tadpoles feed and grow in the pond; adult frogs hunt insects around its edge and return to lay eggs.
Which prediction accounts for more than one life stage?
Build a two-stage cause-and-effect explanation using one pond change for tadpoles and one for adults.
