UNIT 6: Earth's Impact on Biosphere

Which of the following is an example of an invasive plant species found in North Carolina?

• Kudzu

• Red Maple

• Longleaf Pine

• Dogwood

What is the primary way that invasive species are introduced into North Carolina?

• Natural migration

• Human activities

• Animal migration

• Wind dispersal

Which of the following is a negative impact of invasive species in North Carolina?

• Increased biodiversity

• Displacement of native species

• Improved soil quality

• Enhanced pollination

Why might removing invasive species from an ecosystem require careful planning?

• Because it is always easy to remove them

• Because removal can affect native species and ecosystem balance

• Because invasive species are always beneficial

• Because it is illegal to remove any plants

A local river in North Carolina is experiencing a decline in native fish populations. After investigation, it is found that an invasive species has been introduced. What steps should be taken to address this issue?

• Do nothing and hope the problem resolves itself

• Develop a management plan that includes removing the invasive species and monitoring the ecosystem

• Introduce more invasive species to balance the ecosystem

• Stop all fishing activities permanently

An invasive species is a plant or animal that is ________ to an ecosystem.

• not native
• just visiting
• beneficial
• not friendly

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

• Parasitism between kudzu and the native plants
• A predator prey relationship between ground plants and kudzu
• Competition occurring between the native and invasive species
• Commesalism occurring between the kudzo and native plants

1. What makes a species invasive?

• Moving to a new ecosystem and taking resources from natives 
• Not having papers
• Species that can't adapt
• Plants that take up too much space

The graph below shows the correlation between air quality index (AQI) and the incidence of asthma in a densely populated urban area over a five year period. A higher AQI indicates low air quality. 

Which of the following conclusions can be drawn from the graph?

• 1. Improved air quality has led to a decrease in asthma cases.

• There is no relationship between air quality and asthma incidence.

• 1. Increasing air pollution has no effect on human health.

• Worsening air quality is associated with an increase in asthma cases.

Which of the following is NOT considered a natural disaster?

• Earthquake

• Flood

• Volcanic eruption

• Deforestation
