hypothesis about difference between plants without fertilizer and plants with fertilizer?
A hypothesis is a proposed explanation for an observable phenomenon. For a hypothesis to be used in science, one must be able to test it in the form of an experiment. The hypothesis is not just an “educated guess.” Hypotheses should be based on previous observations that cannot be explained with available information. A scientific investigation is designed to test this hypothesis.
Without fertilizers, nature struggles to replenish the nutrients in the soil. When crops are harvested, important nutrients are removed from the soil, because they follow the crop and end up at the dinner table. If the soil is not replenished with nutrients through fertilizing, crop yields will deteriorate over time.
