The pH of the river is very high

Fish caught from the river will be free of parasites

Which of the following best helps to explain why phosphorus is often limiting factor In many ecosystems?

Under many conditions, phosphorus forms stable insoluble compounds

There is usually a gaseous phase in the phosphorus cycle

Phosphorus cycles very quickly through environments

Phosphate is not readily taken up by plants

Factors contributing to the rise in world hunger include all of the following EXCEPT

Increasing consumption of vegetable protein in place of meat protein

Unequal distribution of available food supplies

Increasing rate of population growth

Increasing poverty in developing countries

Which of the following statements about genetic diversity is true?

Genetic resistance to pests and diseases can be increased by crossing a crop plant with ancestral varieties.

Genetic uniformity of a crop increases the crop’s overall resistance to pets and disease.

Genetic engineering technology is used to increase genetic diversity by creating new species with synthetic genes.

Genetic diversity within populations of common crop species such as corn is typically high

Negative environmental impacts associated with large-scale hydroelectric projects have been demonstrated in which of the following area?

Three Mile Island, Pennsylvania

A country with an age distribution like that shown in the figure above, is most likely a country that

Is experiencing slow or no population growth

Is experiencing a high death rate

Which of the following factors is fundamentally responsible for seasons on Earth?

The tilt if Earth’s axis of rotation

The varying distance of Earth from the Sun

The tidal pull of the Sun and Moon

The anthropogenic greenhouse effect

Which of the following describes a fundamental characteristic of the green revolution in food resources?

The development of new strains of crops with higher yields

The application of higher levels of organic fertilizers to increase rice production

Deforestation to provide field crops with increased sunlight for photosynthesis.

The addition of calorie, fat, fiber percentages to the information provided on food packages levels

Critics of incineration of municipal solid waste suggest that it may not be the best solution for the future, for which of the following reasons?

Incineration contributes to air pollution

Incineration produces ash that increases landfill volume

Incineration involves advanced technology

The Polar Regions radiate away more heat energy than they receive from the Sun in the course of a year. However, they are prevented from becoming progressively colder each year primarily by the

transport of heat through the atmosphere and oceans

absorption of ultraviolet radiation by snow

concentration of Earth’s magnetic field lines at the poles

Release of the latent heat to the atmosphere when the polar ice caps melt

An advantage of recycling aluminum rather than disposing it in landfills is that aluminum can be

produced from recycled metal using much less energy than is required for its production for aluminum ore

produced from ore that is chemically reactive and dangerous to transport, store, and process

produced from ore that is scarce and found primarily remote, inhospitable regions at high latitudes

absorbed by plants and then biomagnified in both terrestrial and aquatic food chain

As urbanization increases and natural soils surfaces are covered, the groundwater supply is reduced due to

increased evaporation and transpiration

Which of the following methods of agricultural irrigation results in the loss of the least amount of water by evaporation?

Conventional center-pivot irrigation
