This color ends in "urple"
What is purple?
100
Define species richness.
the # of different species in an area
100
A food chain consists of grass, rabbits, and wolverines. This species would be the primary consumer in this food chain.
What is a rabbit?
100
What does the dashed line on this graph represent?
Carrying Capacity (K)
100
What are the four main biogeochemical cycles to know about (from Unit 1)?
Nitrogen, Phosphorous, Carbon, Water
200
Describe one provisioning service that a forest ecosystem could provide.
Forests can provide lumber / food resources for other organisms.
200
Define species evenness.
the relative abundance or proportion of each species in the community
200
Name two biomes that have a low amount of rainfall.
Tundra & Desert - they differ by their temperatures.
200
What type of reproductive strategists would elephants be considered?
K-strategists
200
Removing trees in an area would affect the Carbon cycle in this manner...
Atmospheric carbon dioxide levels will increase due to a reduction in photosynthesis in the area.
300
Owls eat blue jays. If 50 joules of energy are available to blue jays at their trophic level, how many joules of energy would be available to Owls?
5 joules of energy
300
Name the 3 primary types of Biodiversity. (100 pts each)
Genetic, Species, Ecosystem
300
Which biome does this Climatogram best represent?
Tropical Rainforest, warm temperatures and large amounts of rainfall in wet season
300
What type of survivorship curve would insects commonly have?
Type III
300
In the nitrogen cycle, this is the process that removes nitrogen directly from its largest reservoir
What is Nitrogen fixing / Nitrogen fixation
400
This is a common pioneer species found during primary succession that helps break down bare rock and turn it into early soils.
What is moss / lichen?
400
Describe an area in which secondary succession would occur.
Secondary succession occurs somewhere there has been life before, but the ecosystem has been disrupted by a disaster. This leaves a soil layer behind for secondary succession to begin.
400
Describe an adaptation an organism would need to have to survive in an intertidal zone.
They would need to be able to withstand different amounts of water & oxygen due to living where land meets water. They may need to be able to attach to surfaces.
400
Which demographic transition stage is Afghanistan in based on this Age Structure Diagram?
Stage 2, (high birth rates, low death rates, population is increasing rapidly)
400
Elevated levels of Nitrogen and/or Phosphorus in an ecosystem can lead to this unfortunate effect in aquatic ecosystems.
What is Eutrophication?
500
A population's crude birth rate is 20 (per 1000 people)
A population's crude death rate is 8 (per 1000 people)
The population's growth rate is...
1.2%! (20-8)/10
500
Name one example of a density dependent and density independent factors that influence population growth:
Density-dependent - competition for resources like food & shelter, disease spread, waste accumulation
Density-independent - Floods, Hurricanes, other natural disasters. Atmospheric pollution.
500
What is the equation for Primary Productivity?
NPP = GPP - R
500
These two stages in the demographic transition model show human populations as relatively stable
What are stages 1 and 4?
500
This is the largest reservoir of Phosphorus in the Phosphorus Cycle
What are rocks and sediment?
