5 multiple choice 1 point the trapping of heat in the earths atmosphere by certain gases is called the _ effect. greenhouse thermostat homeostasis global warming 6 multiple choice 1 point an endemic species is highly vulnerable to extinction because it is found in one particular location an invasive species a species that causes disease 7 multiple choice 1 point who should help shape environmental policy? scientists who understand ecosystem function elected officials informed citizens all of these groups should work together to create sound environmental policies. 8 multiple choice 1 point which factor is responsible for causing the most animal extinctions? predation habitat loss introduced species species overexploitation

Explanation:

• Question 5: The greenhouse effect is the trapping of heat in the Earth's atmosphere by certain gases like carbon dioxide. A thermostat is a device for regulating temperature. Homeostasis is the ability of an organism to maintain a stable internal environment. Global warming is the long - term heating of the Earth's climate system, which is a consequence of the greenhouse effect.
• Question 6: An endemic species is highly vulnerable to extinction because it is found in one particular location. An invasive species is a non - native species that causes harm. A species that causes disease is a pathogen.
• Question 7: Scientists who understand ecosystem function can provide scientific knowledge, elected officials can make policies, and informed citizens can advocate for and support environmental policies. So all of these groups should work together to create sound environmental policies.
• Question 8: Habitat loss is the leading cause of animal extinctions as it destroys the living spaces of animals. Predation is a natural process (though over - predation in some cases due to human - introduced predators can be an issue). Introduced species can cause problems but habitat loss is more widespread. Species over - exploitation (not over - replication) is also a significant cause, but habitat loss is the most common major cause.

Answer:

1. greenhouse
2. Highly vulnerable to extinction because it is found in one particular location
3. All of these groups should work together to create sound environmental policies
4. Habitat loss
