Which of the following practices would be a way that a farmer could grow crops organically?

Planting crops at times when the bugs are not around to eat them.

The huge demand for fuelwood for cooking in developing countries is leading to a downward spiral of environmental degradation. All of the following have resulted from the overuse of this resource EXCEPT: Poverty Disease Preservation Crime violence

Cutting the intermediate-aged trees in an uneven-aged forest is referred to as: Selective cutting Clear-cutting Strip cutting Seed-tree cutting deforestation

Selective cutting

Which of the following techniques helps to limit soil erosion?

Terracing

Raising fish in underwater pens is one way to solve the overharvesting problem. This is known as

aquaculture.

An area that is especially rich in plant species that are found nowhere else and are in great danger of extinction are known as: Biodiversity hotspots Wilderness areas National parks Nature preserves Protected areas

biodiversity hotspots

DDT is an example of a pesticide that entered the food chain and worked its way up, resulting in higher concentrations. This is known as

biomagnification

A method of using biological control to control pests is to

bring in natural enemies such as predators, parasites and bacteria.

A farmer in a developing nation will try to put the maximum amount of crops on his land. This farmer would most likely use which method of tree cutting? Selective cutting Clear-cutting Strip cutting Seed-tree cutting Shelterwood cutting

clear cutting

One way to successfully incorporate genetic engineering is to

cross a crop plant with a native variety.

Many crops are now being engineered so that pests do not eat them. These are called

genetically modified crops (GMOs).

A protected area that allows the migration of individuals and populations to move from one area to another is known as a(n): Buffere zone Fragmentation Eutrophication Sequestration Habitat corridor

habitat corridor

natural control of pests.

Sale of exotic pets and plants

overexploitation

DDT was a very effective pesticide; however, it remained in the environment for years. This is known as

persistence

One effect of our overgrazing of the natural rangelands is -Increased biodiversity -Decreased solar power -Inversion of the human population pyramid -Soil erosion -Increased soil porosity

soil erosion

A more sustainable form of meat production is to

switch to poultry and farm raised fish.

The goal of Integrated pest management is to

utilize biological, chemical and cultivation techniques in a coordinated way to eliminate pest species.
