William compared two soil samples to check soil’s ability to support the growth of plants. He had read that plants grow best in soil rich in humus. The experimental data is summarized in the table.

What conclusion can be BEST drawn from the data?
A) Soils rich in humus improve plant growth.
B) Earthworms do not improve the soil’s humus content.
C) Plants will not grow in soils that do not have earthworms.
D) The growth of plants is poor in soil that has decomposed organic matter.

A) Soils rich in humus improve plant growth.

Explanation:

Humus improves the organic matter content in the soil, so the soil has the ability to provide plants with a malleable soil, rich in nutrients and with a vast and healthy population of microorganisms. All of this allows plants to grow less and their production capacity to be stimulated.

Well based on that and based on the results of the experiment shown above, we can say that soils rich in humus improve plant growth.
