,The Amazon River basin is globally important because it has ... one of the world's greatest carbon sinks.
case study chapter 1
How does the Amazon River basin influence climate - by capturing carbon in growing trees
conditions? (check all that apply) - by recycling rainfall that is essential for agricultural regions
- by storing carbon in standing trees
- by transpiring moisture that then falls in the forest
Forests in the Amazon basin are being lost to ... agricultural land conversion, especially beef and soybean production.
Indigenous populations in the Amazon region (check all that - have legally protected land rights.
apply) - are important in the struggle to protect the forests.
- collaborate with conservation groups for forest protection.
Restoration of the Amazon rainforest probably includes... agroforestry and natural regeneration.
Practices and policies around the world matter in the Amazon Amazon forest losses result from land conversion for global food markets and global
because... investors.
What units are used for the dependent variable? Figure 1 global hectares per person
What are the lowest and highest values on this axis? 0, 12
Which component (color) is the greatest for the top 10 carbon emissions, cropland
countries? For the bottom 10?
For the United States, what is the total footprint per person? 7 global hectares per person
What proportion of the total footprint for the United States is approximately 70%
represented by carbon emissions?
Approximately what proportion of the total footprint for the approximately 15%
United States is represented by croplands?
For Denmark, what is the total footprint per person? approx. 8 global hectares per person
, What proportion of the total footprint for Denmark is just over 25%
represented by carbon emissions?
Approximately what proportion of the footprint for Denmark approx. 35%
is represented by croplands?
Algae are photosynthetic, which means they produce oxygen The additional plants and algae eventually die and cause an increase in decomposers
as part of their metabolic processes. How then does algae that use up the oxygen.
growth cause hypoxia in water? Case study chapter 2
What term is used to describe an aquatic or marine system Eutrophication
that has increased nutrients and thus increased plant growth?
Which of the following nutrients are responsible for the dead - Nitrogen
zone in the Gulf of Mexico? Select all that apply. - Phosphorus
Nitrogen cycles through living and nonliving systems. This - NH4 (ammonium)
biogeochemical cycle is important to understand because it - NO3 (nitrate)
strongly influences how ecosystems function. Using the - NH3 (ammonia)
diagram and your knowledge of the nitrogen cycle, answer
the following questions. Which forms of Nitrogen can plants
take up? Check all that apply.
Section 2.5 p.45
Plants capture N2 from the air. False
Refer to section 2.5. in your textbook. nitrogen fixation by bacteria
How is N2 captured, or fixed, from the air into the food web?
What is the difference between nitrogen-fixing by bacteria Anthropogenic sources fix far more nitrogen than bacteria.
and by anthropogenic sources (fossil fuel or commercial
fixation)?
If anthropogenic processes introduce increasing amounts of - it can form nitrous oxide, a greenhouse gas
atmospheric nitrogen to the biosphere and hydrosphere, - It enters aquatic systems, stimulating plant and algae growth.
where does that nitrogen go? Check all that apply. - It fertilizes crop fields.
Why is Nitrogen so important for living organisms? It is used in organic molecules including the amino acids that form proteins.
