Answer:
Taking more samples from different parts of an acre.
Explanation:
Validity and accuracy of the data is crucial for any serious research. In this particular case, the most accurate data would be obtained if earthworms would be counted on the whole acre. Of course, this would consume lot of time, people, money etc. That's why methods for estimation are used. Estimation best works with large number of samples. Since one acre equals over 4000 square meters, taking only five samples from such a big area is simply not enough for obtaining valid data.
One of the possible ways to improve estimation is to take more samples per acre while avoiding taking adjacent samples because it could be possible that number of earthworms in one part of an acre is increased (or decreased) for any reason, which would lead us to wrong conclusion.

I’m not sure if that’s the answer but what immediately pops up in my mind is the food chain. Primary consumers (herbivores) consume producers (plants). Secondary consumers consume primary consumers etc. At the end of the day, all kinds of animals die and decompose, providing nutrients for producers to grow, continuing the circle of life.
Lion is a top predator that hunts secondary consumers. Simba’s father died and contribute to the circle of life. I hope it gave you some pointers!
