Answer to Question 1

F

Answer to Question 2

Increase water-holding capacity
Provide pore space, which enhances aeration that is critical for good plant growth
Prevent small particles of clay from producing a solid mass, thereby enhancing root
growth
Regulate soil temperature
Release small amounts of nitrogen and other nutrients as it decays
Increase the cation exchange capacity (CEC), which is a measurement of the soil's
ability to hold nutrients
Promote the growth of microorganisms, which in turn helps to condition the soil
