Explanation:

For question 4, 'biota' refers to the living organisms in soil. pH is a measure of acidity or alkalinity, parent - material is the underlying geological material from which soil forms, and topography refers to the shape of the land surface.

Pieces of rock that have been split apart are related to parent - material or weathering products, pore spaces are the voids in soil, and liquids are just one component of the soil environment but not organic matter.
