• nutrient cycle.

Multiple Choice

What role does precipitation play in the water cycle?

• Keeps moisture in a gaseous state

• Controls rate of air movement in the soil

Multiple Choice

Why is capillary water an important source of groundwater?

• Makes up aquifers and underground streams

• Plant roots can absorb or take it up

Multiple Choice

Permeability is the rate of movement of what through the soil?

• Air and fertilizer

• Water and air

• Water and fertilizer

• Water and microorganisms

Multiple Choice

As a society, if we wish to conserve water and improve water quality, we must:

• ask the right questions about our use of water.

• stop drinking water.

• stop brushing our teeth so often.

• stop fertilizing our gardens.

Multiple Choice

Multiple Choice

The smallest soil particle is:

• clay.

• gravel.

• sand.

• silt.

Multiple Choice

Spaces between soil particles that permit root penetration and store air, water, and nutrients are called:

Multiple Choice

If planting trees is the most intensive recommended land treatment, the likely land class is:

• I.

• II.

• IV

Multiple Choice

What is the best description for "No till" as a cropping technique?

• Crops are planted in the residue of a previous crop without plowing.

• Geese are used as the major source of weed control.

• Plowing is done prior to planting.

• Used only when the farmer is not concerned with soil erosion

Multiple Choice

When a farmer leaves crop residue standing, the most likely result is:

• a decrease in the wildlife population due to starvation.

• an increase in wildlife population due to increased food supply.

• increased competition from wildlife for the food supply

• sick wildlife that are poisoned by pesticides

Multiple Choice

Mr. Langdon left a brush pile when harvesting his woodlot. Why is it a good management practice for improving wildlife?

Multiple Choice

No area of U.S. land is more important to wildlife than:

• backyards.

• forests.

• ponds.

• wetlands.

Multiple Choice

A decrease in habitat quality is often the result when:

• carrying capacity is more than the number of wildlife living in the habitat.

• more than one type of wildlife live in a habitat

• population of wildlife in habitat is more than the carrying capacity

• the habitat is too large for the number of wildlife.

Multiple Choice

Hunting and fishing are wildlife management practices which help reduce which pressure upon wildlife populations?

• Excess animal populations

• Introduction of non-native species

• Standing crop residue

• Too much carrying capacity

Multiple Choice

What type of stress can cause some animals to slow down or stop reproducing altogether as a result of malnutrition?

• Hunting

• Killing

• Overpopulation

• Overeating

Multiple Choice

Carrying capacity refers to the

• zone of transition between the different habitat factors

• amount and kind of food an animal can eat.

• number of gallons of water a stream supplies

• number of wildlife the habitat can support

Multiple Choice

Which is most true of the relationship of hunting to wildlife?

• Increases the number of animals competing for the food supply

• Removes some game that would otherwise be lost due to natural causes

• Endangers some wildlife species

• Takes the place of natural predators

one cutting is:

• clear cutting.

• prescribed burning.

• prescribed thinning.

• selection cutting.

Multiple Choice

What is selection cutting?

• Cuttings made in a stand of trees before harvest takes place

• Harvesting in a forest of trees of different ages and mixed species

• Harvesting where all the trees in a forest are to be cut at once

• Removal of forest litter to prevent forest fires

Multiple Choice

The least expensive method of replacing trees harvested from the

woodlot is:
