an increase in marine ecosystem stability

Global warming has been linked to a decrease in

the rate of carbon dioxide production

Which human activity would preserve nonrenewable resources?

removing carnivores from a forest

heating homes with fossil fuels

The acidity of a local stream would most likely be affected by

a change in the percentage of decomposers living in the stream

Deforestation by burning has been described as a "double whammy" to the environment, meaning it has 2 negative impacts. Why is this description accurate?

Forest burning releases CO 2 while decreasing oxygen, which disrupts cycles

Deforestation reduces the amount of oxygen in the atmosphere, which depletes the ozone layer

Forest clearing is often followed by land development, which often leads to increased noise pollution

Deforestation increases the number of plant and animal species by destroying habitat

Approximately 75 percent of the Earth's surface is covered in water. So why is water considered such a precious resource?

Only a small fraction of the Earth's water is freshwater available for drinking and irrigation

The greenhouse effect is causing most of the world's freshwater to be trapped in the atmosphere

Each year, more freshwater is being trapped in icecaps located at the North and South Poles

Global warming caused by greenhouse gas emissions will likely cause Earth's oceans to evaporate

Many common products, such as wooden furniture, paper, and books, are made from trees. Which of the following is a likely consequence of humans cutting down a forest in order to make use of the natural resources there?

the decrease of chemical runoff into the oceans

the increase of light pollution in cities

the interaction of sunlight with pollutants produced by fossil fuels

What are renewable resources?

Resources that can replenish themselves over time

Resources that are used faster than they form

Resources that exist only in urban areas

Resources that exist only in rural areas

Human activities that degrade ecosystems result in a loss of diversity of the living and nonliving environment. Two ways in which humans frequently harm ecosystems and affect other organisms is through land use and pollution. How does land use cause a reduction in biodiversity?

It decreases the space and resources available to certain species

It causes herbivores to become carnivorous

It provides a more hospitable living environment

It causes all the natural Earth cycles to stop

Humans often change ecosystems as a result of population growth, consumption, and technology. Which of the following exemplifies a way in which humans modify ecosystems?

factory and automotive emissions causing acid rain

redirecting and storing freshwater behind dams

cutting down trees to build new buildings and roads

Biodiversity refers to

the variety of species on Earth

What effect will an invasive species have on the carrying capacity of an ecosystem?

The carrying capacity will only decrease for those in competition for same resource

The carrying capacity will increase

The carrying capacity for everyone will decrease

The carrying capacity for all animals will stay the same

Kudzu has overgrown many parts of southern Missouri and native ground plants have disappeared from the area. This is an example of:

Competition occurring between the native and invasive species

Parasitism between kudzu and the native plants

A predator prey relationship between ground plants and kudzu

Commesalism occurring between the kudzo and native plants

causes sea levels to rise because it adds water to the ocean.

does not cause sea levels to rise because the water fills the space left by the melted sea ice.

Which of the following is the best conclusion that can be made from this graph?

atmospheric carbon dioxide levels have increased steadily since 1960

atmospheric carbon dioxide levels have been decreasing since 1960

Hawaii has a lot of carbon dioxide

humans have been working hard to decrease carbon dioxide levels

How does the concentration of carbon dioxide in the atmosphere affect climate?

As carbon dioxide concentrations increase, temperatures increase

As carbon dioxide concentration increase, temperatures decrease.

Carbon dioxide concentrations have no affect on climate

As carbon dioxide concentrations increase, temperatures become more random.

This graph shows the sources of the nitrogen entering the Gulf of Mexico as pollution. What is one conclusion you can make based on the information in the graph?

Most nitrogen pollution found in the Gulf of Mexico comes from farming crops.

Nitrogen that comes from the atmosphere is more harmful than nitrogen that comes from crops.

Corn and soybeans are the only crops associated with nitrogen pollution.

Nitrogen is not a problem in the Gulf of Mexico.

What is one way humans are trying to positively impact the ocean?

Transporting goods in ocean vessels

Which of the following is NOT a source of pollution in the ocean?

Sand drifting along the bottom of the ocean floor.

Nitrogen and phosphorus from fertilizers used on land.

Emissions from gas-burning vehicles.

increase environmental carrying capacity

increase the stability of ecosystems

Albert wants to practice conservation. He has decided to examine his lifestyle in order to identify areas in which he can reduce the resources he consumes, reuse resources he already has, and recycle resources that he cannot reuse. In which of the following ways can Albert best reduce the resources he currently consumes?

Ride a bike to work instead of taking his car

Use paper grocery bags as gift wrap

Subscribe to a daily rather than a weekly newspaper

Use an organic rather than synthetic fertilizer in his garden

Which of the following historical events most likely triggered the largest increase in the human population?

the Industrial Revolution, which began in the late 1700s

the Black Death plague, which occurred in the mid-1300s

the domestication of wheat crops, which began around 8000 B.C

the fall of the Roman Empire, which occurred around A.D. 800

New fuels are being produced by converting corn and grasses into compounds containing alcohols that can be broken down for energy in various engines. The purpose of this research is to

reduce the use of nonrenewable resources.

increase the rate of air pollution.

reduce the rate of homeostasis in organisms.

cause a loss of biodiversity in the rain forests.

The presence of wastes, such as plastic bags and motor oil, in lakes and streams miles away from developed areas suggests that

ecosystems are interconnected and human action can alter ecosystem equilibrium.

recycling programs have failed to conserve biotic resources.

natural processes can alter ecosystem stability.

direct harvesting practices have led to irreversible destruction of ecosystems.

The northern elephant seal was almost hunted to extinction in the 1800s. By the late 1890s, approximately one hundred seals were left, reducing the gene pool of the population. What will be the consequence of this reduction?

The elephant seals will be more vulnerable to environmental change.

Competition within the population will increase.

The surviving elephant seals will be better able to adapt.

Inbreeding will be less frequent among the remaining population.

When fertilizers run off farmland into streams and ponds, the nitrogen content of the water increases. This can lead to rapid growth of algae in a process called eutrophication. How can this process affect other organisms in the water?

Oxygen is used up as algae is decomposed, reducing the amount available to other organisms.

The water becomes better able to support aerobic organisms.

The algae provide food for fishes and other organisms, leading to decreased algae populations.

The extra nitrogen provides additional food for the other organisms, increasing their population.
