Unit 6

What is global warming?

• the normal temperature fluctuations of Earth's climate cycle

• the melting of the polar ice caps

• the trend of increasing temperatures on Earth

• the changes in Earth's biosphere that affect the atmosphere

How might an introduced plant species kill native plant species?

• It's rapid growth can deprive native plants of sunlight.

• Its rapid growth can deprive native plants of food.

• It can cause soil loss from erosion.

• Its rapid growth can deprive native plants of oxygen.

1. Why might an introduced animal species overrun native species in an ecosystem?

• . Its population size is smaller than those of native species.

• . It is more energy efficient, so it eats less food.

• It is a predator of the native species.

• It often has no natural enemies

Global warming has been linked to a decrease in 

• the size of the polar ice caps 
• the temperature of Earth 
• the rate of species extinction 
• the rate of carbon dioxide production

Which human activity is correctly paired with its likely future consequence?

• overfishing in the Atlantic — increase in supply of flounder and salmon as food for people 
• development of electric cars or hybrid vehicles — increased rate of global warming 
• use of fossil fuels — depletion of underground coal, oil, and natural gas supplies 
• genetically engineering animals — less food available to feed the world’s population

Deforestation of areas considered to be rich sources of genetic material could limit future agricultural and medical advances due to

• the maintenance of dynamic equilibrium 
• the loss of biodiversity 
• an increase in the ecosystem’s carrying capacity
• the depletion of the ozone layer

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 CO₂ 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

In lakes in New York State that are exposed to acid rain, fish populations are declining.  This is primarily due to changes in which lake condition?

• Biotic Factors
• ozone levels
• increased sunlight (optional)
• pH
