The soil order best associated with dry climates:

Tropical rain forest (broadleaf evergreen forest) are found in areas of:

Tropical rain forest (broadleaf evergreen forest) are found in areas of:

The base (foundation/fundamental unit) of any food chain converts solar energy and nutrients to food and consists of:

The following quote from a textbook describes a vegetation type listed below. Which one? “…biological variation, in terms of the number of plant and animal species per unit of area, is far greater…than elsewhere…the vegetative response to a climate that exerts virtually no constraints on plant growth — a climate that provides abundant energy and moisture in every month of the year. The resulting vegetation is dominated by tall trees.”

Soils in dry desert environments often are relatively fertile because:

Mollisol soils with a good A-horizon(topsoil) and relatively high fertility can likely be found in:

As water percolates down through the soil profile, it has a tendency, over time, to wash (translocate) clay particles, organic matter, and other materials from the ________ horizon (by eluviation – removal) to the _______ horizon (by illuviation and subsequent accumulation) in a process called podzoliztion.

The general long-term effects of fire on prairie plant communities is:
