Unit 1
Does oceanic absorption of carbon dioxide increase or decrease H+? Also, does this increase or decrease pH?
Increases H+ because it makes ocean more acidic which in turn decreases pH.
The peak conditions that a species can exist.
optimum range/condition
density dependent
An estimate of how much a molecule of any compound can contribute to global warming over a period of 100 years relative to one molecule of CO2.
What is Greenhouse warming potential (GWP)?
Name a factor that could be used to determine a country's impact on the environment.
population, affluence, technology, education
Identify 3 major carbon reservoirs
sedimentary rock (limestone), fossil fuel deposits, soil organic matter, atm carbon dioxide, old-growth trees
The first species to move into an unoccupied area.
pioneer species
The type of survivorship curve is shown by high survival throughout the lifespan, with individuals dying off at an old age.
type 1
A 1973 treaty formed to control the international trade of threatened plants and animals.
What is the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES)
a developing country would be expressed as this type of shape on the age structure diagram
pyramid
Describe the 10% Rule. What is the exception to the 10% Rule?
only 10% of energy moves to next level and the exception is the transition from the sun to producers, in which case only 1% of energy is retained.
species richness
a mouse is an example of this type of species.
r-selected
A process in which an increase in ocean CO2 causes more CO2 to be converted to carbonic acid, which lowers the pH of the water
What is Ocean Acidification?
the resource in an ecosystem that is too low to allow further population growth
limiting resource
Briefly describe the 5 steps of the nitrogen cycle.
1. nitrogen fixation
2. nitrification
3. assimilation
4. ammonification
5. denitrification
An organism that can signal changes in its environment, and can be used to help assess the health of an ecosystem.
indicator species
population graphs that show a s-shaped curve is this type of growth model
logistic
Chemical that can be used for cooling refrigerators and air conditioners.
What are CFCs (chlorofluorocarbons
The amount of energy available to a secondary consumer, if 15,000 kcal of chemical energy is stored in organic compounds.
150 kcal
Why is the npp of the open ocean low?
large expanse of the ocean supports enormous number of producers
A symbiotic fungi and algae that typically is the first colonizer of bare rocks.
lichen
What is the doubling time of a population that has a 5 percent growth rate?
14
A commitment by 24 nations to reduce CFC production by 50 percent by the year 2000
What is the Montreal Protocol
When species use limiting resources in different ways, places or times to reduce competition.
What is resource partitioning
