Based on the results of Experiments 1 and 2, which of the following statements is most accurate?
F. The presence of fungi has little or no impact on plant growth.
G. Removing fungi from soil can help to increase growth in some plants.
H. The presence of certain fungi in the soil increases plant growth.
J. Fungi cannot survive in local greenhouses.

Experiment 1
For 6 weeks, several specimens of three different types of plants, selected from among four different types of plants, were grown in a greenhouse. The average growth of each type of plant was recorded every two weeks. The soil used for the plants was treated to remove any trace of fungi to establish expected growth without the plant-fungi association. The results are shown in Table 1.

Experiment 2
In this experiment, several specimens of four different types of plants were grown in a greenhouse for six weeks, and the average growth of each type of plant was recorded every two weeks. This time, however, untreated soil that contained fungi was used. The results are shown in Table 2.
