Steve studied the factors that affect the decomposition (breakdown) of vegetable matter by soil microbes (bactería). He put four pieces of carrot that were equal weight into each of the three plastic bags filled with soil. He added different amounts of water to each bag and kept them all at room temperature. Every two days, Steve removed the carrot pieces from each on
to weigh them. Which hypothesis was Steve most likely testing in his experiment?
O if the weight of the decomposing matter is increased, then the rate of the decomposition will decrease.
If the temperature is reduced, then there is an increase in decomposer activity.
X
If the soll type is changed, then the rate of decomposition will decrease.
O if the moisture content of the soil is increased., then there is increase in decomposer activity
