B
Which of the following is not a greenhouse gas? Co2 Co H2O (g) Methane
B
Looking at Trophic efficiency in terrestrial systems, what percent of the net primary productivity moves directly into dead organic matter? A. 25% B. 45% C. 16% D. 96%
D
Where is the majority of the carbon found and how much carbon from earth is found there?
It is found in the oceans, and about 56% of all carbon is found there.
T/F: Species moving towards the poles at a rate of 6.1 km/decade is a sign of climate change.
T
By what year and how much of Africa's land will no longer be able to grow maize and will transition from mixed crop and livestock systems to livestock-only farming systems.
VAnswer: By the year 2050, climate change will affect 3% of Africa's land in the way of being able to produce crops.
Question: List 2 of the 4 greenhouse gases
Water Vapor (36-70%) CO2 (4- 26%) Methane (4- 9%) Ozone (3- 7%)
T/F C3 photosynthesis can be as efficient as C4 photosynthesis if carbon dioxide concentrations are high.
answer: T In the corn and wheat example, increased co2 concentrations caused the wheat to perform better but did not change the corn. Wheat is a C3 plant while corn is a C4 plant.
What is an example of an invasion by disease causing organisms?
answer: malaria parasite
Which of the following is not a major greenhouse gas? A.Methane B. Helium C. Water Vapor D. Ozone E. Carbon Dioxide

c
Which of the following is NOT a major greenhouse gas?
c
Which of the following is the correct order of carbon sinks largest to smallest? a.) atmosphere, soil, ocean, plants b.) plants, soil, atmosphere, ocean c.) ocean, atmosphere, soil, plants d.) ocean, plants, soil, atmosphere
c
Which of these is NOT a result of global warming? A) Speeding of flowering and breeding events B) Species are moving towards the poles C) CO2 concentrations are decreasing D) Disease and vectors are extending their range
c
What expanse the range for animals?____
disease abd vectors
A majority of CO2 (carbon dioxide) is found in the atmosphere.
f
Global warming is mainly due to CO2 by fossil fuels and animal grazing.
f
T/F Global warming and CO2 increase plant primary production.
f
True or False. In greenhouse gases there should be some traces of sulfur hexafluoride, hydroflurocarbons, and CFCs.
f
True or false: Only 44% of CO2 accumulates in the atmosphere despite CO2 increasing in the past few decades.
f
True/False Greenhouse studies provide a better outlook of the individual plant responses to increased CO2 than Free Air Carbon Enrichment (FACE)
f
The __________________________ is the process in which the emission of infra red radiation by the atmosphere warms the planet's surface.
greenhouse effect
Global warming is mainly due to higher [CO2] levels that are a result of burning fossil fuels and clearing forested land. T/F
t
Q: Water vapor is a major greenhouse gas.
t
T/F: The increase concentration of carbon in the atmosphere is helping C3 plants do just as well as C4 plants.
t
True or False Global warming is expected to aid malarial spread to the United States.
t
True or False: Species are gradually moving towards the poles due to climate change.
t
True/false: The greenhouse effect is the process in which the emission of infra red radiation by the atmosphere warms the planet's surface.
t
Global warming has been underway since the 1970s.
true
True or false? The climate impacts all populations and all communities.
true
True/False As a result of global warming, diseases and vectors are extending their range.
true
What are two major components of climate change?
1- increasing temperature 2- changing precipitation
List three ways in which Global Warming is affecting life on earth?
1. Speeding flowering and breeding events 2. It is allowing animals to move towards the poles 3. Diseases and vectors are extending their range
Q: What is green house gases?
A: gases present in the Earth's atmosphere that reflect infrared radiation back to Earth, thus warming it. The most important ones affected by humans are carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons. Water vapor also acts as a greenhouse gas.
Q: What form of energy is retained by Greenhouse Effect, and what are the top two contributing gases?
A: infrared radiation; water vapor (36-70%) and CO2 (9-26%)
What are the climate factors that impact all populations and communities?
A: temperature, rainfall, wind, solar radiation
Two examples of impacts that are caused by global warming are __________ and __________.
Answer: Animals can move closer to the poles. Disease parasites are extending their range. Spring is beginning earlier causing plants to flower sooner.
Multiple Choice: Which is NOT a way how an increase of the concentration of carbon dioxide will affect other factors of individual plant responses? A) Decrease in stomatal conductance B) C4 photosynthesis plants benefit and yield is increased C) Increase in reproductive output D) C3 photosynthesis plants benefit and yield is increased
Answer: B) C4 photosynthesis plants benefit and yield is increased
The majority of carbon in the carbon cycle can be found where? A) Land Plants B) The Atmosphere C) Deep Oceans D) The Sediment
Answer: C, very deep in the oceans.
With increased carbon dioxide concentration, C3 plants are not effected.
False, C4 plants are not effected
Which of the following is a factor that contributes to climate? A. Temperature B. Rainfall C. Wind E. All of the above.
E
True / False The CO2 levels currently on Earth are directly affecting animals.
