Which of the following statements about soil is not correct?

a)

b)
the properties of soil are dependent only on nonliving components.
c)
the properties of soil can influence the productivity of plant life.
d)
organic material is an important element of soil.
e)
soil properties are affected by climate.

B)The properties of soil are dependent only on nonliving components.

Explanation:

Soil is dependent on both living and nonliving components because it relies on weather and climate as well as nutrients provided by decomposers.

B)  The properties of soil are dependent only on nonliving components.

Explanation:

The soil properties depend on both living and non-living components of soil. The living components of soil such as decomposers (earthworm, etc.) breakdown the dead organic matter and add nutrients and humus to the soil. Humus-Rich soil is considered fertile and more suitable for plant growth.  

Similarly, the nitrogen-fixing bacteria present in soil fix atmospheric nitrogen into a biologically useful form and thereby regulate the nitrogen content of the soil.

Hence, properties of soil such as fertility, mineral content, etc. are determined in part by its living components.
