Ecosystems & Energy
This is the total energy available to consumers
NPP
What process releases water vapor from plants?
Transpiration
This term refers to variations within a species.
The average children a female has in a population is known as this.
total fertility rate
What causes high death rates in phase I of demographic transition?
infant mortality (Sam should know this because he is so obsessed with death)
Which biome is dominated by grasses and has long dry seasons?
Savanna
Name a major carbon sink.
ocean, limestone, plants (may accept atmosphere but the others are better)
What anthropogenic activity could cause an organism like mosquitos to evolve?
Pesticide use
What does a wide base in an age diagram indicate?
rapid growth
Name one benefit of intact forests.

10%
In this process, bacteria convert nitrogen gas into usable forms.
nitrogen fixation
Bees pollinating plants whilst making honey is an example of this.
mutualism
What happens to birth and death rates during industrialization?
decline or drop
This creates a dry side and a wet side of a mountain.
rain shadow effect
Warblers feeding in different parts of a tree is an example of this
resource partitioning
This part of the water cycle occurs when water infiltrates groundwater reservoirs.
Recharge
This will indicate the health of an ecosystem.
keystone species (maybe accept indicator species)
What two things are equal if there is zero population growth?

Dams alter water flow, obviously. What else do they prevent from flowing naturally?
Sediment
Why do phytoplankton stay near the water's surface?
Sunlight!
What important aspects of an organism utilize phosphorus?
DNA and ATP
What could decimate crops with a low genetic diversity?
Disease (or pests, but disease is a better answer)
How does industrialization affect growth rates long term?
reduces them
What’s a downside of genetically engineered crops?
lower genetic diversity
