Biomagnification and Greenhouse Gasses Review

What might happen if the greenhouse effect didn't exist?

• It would be too cold for humans to survive on earth.

• The earth wouldn't have an atmosphere.

• The earth's temperature would be much more comfortable.

• The sun's rays would never reach the surface of the earth.

Which of the following is NOT a greenhouse gas?

• Water vapor

• Carbon dioxide

• Methane

• These are all greenhouse gasses.

How do greenhouse gasses keep the Earth warm?

• They trap the heat from sunlight in order to warm Earth's atmosphere.

• They reflect the sunlight rays and keep heat out of Earth's atmosphere.

• They trap the heat from the Moon.

• They trap the heat created from air pollution in order to cool the atmosphere.

How is the greenhouse effect similar to a real greenhouse?

• They both trap the sun’s rays and keep the inside warm.

• They both trap the sun’s rays and keep the inside cold.

• They both contain greenhouse gasses.

• They both work best at night.

Which of the following greenhouse gasses is increasing rapidly in the atmosphere?

• Ozone

• Chlorofluorocarbons (CFCs)

• Water vapor

• Carbon dioxide

Which organism in the food chain would contain the highest level of chemical pollutants?

• The grass would contain the highest level because it is the producer.

• The grasshopper would contain the highest level because it is the primary consumer.

• The mouse would contain the highest level because it is the secondary consumer.

• The owl would contain the highest level because it is the tertiary consumer.

Refer to the food chain diagram. Which organism in the food chain would contain the lowest level of chemical pollutants?

• The producer would contain the lowest level of chemical pollutants.

• The primary consumer would contain the lowest level of chemical pollutants.

• The secondary consumer would contain the lowest level of chemical pollutants.

• The tertiary consumer would contain the lowest level of chemical pollutants.

Chemical pesticides tend to be used in terrestrial ecosystems, but they are commonly found in the tissues of aquatic organisms. Because of this, birds and other animals with a diet high in fish commonly suffer the effects of biological magnification. How do these pesticides end up in these aquatic ecosystems?

• Pesticides evaporate and are delivered to water sources by rainfall.

• Land animals containing pollutants die and decompose in waterways.

• Pesticides are carried to water sources by freshwater runoff.

• Pesticides are deposited in water sources through bird waste.

• Global warming

• Acid Rain

• Methyl Mercury

Which of the following is an example of a toxin or pollutant responsible for biomagnification?

• DDT and other pesticides

• Acid rain

• Burning fossil fuels

• Renewable resources
