What do we call the dotted line labeled "D"
Public
Carrying Capacity
What is a "limiting factor"?
Something that limits the species of a population in an ecosystem
How does the predator-prey relationship affect each other's population?
They control each other population.
The movement of organisms into an area?
Immigration
Burning fossil fuels releases what gas?
CO2/ Carbon dioxide
A group of the same species, living in the same area.
Population
Define "Carrying Capacity"
the maximum number of individuals of a population that the environment can support is the...
Disease (bacteria), food availability, predators, etc.
The number one reason for biodiversity depletion is due to ?
Human Activity ( Deforestation, urbanization....)
The movement of organism out of an area?
Emigration
Which cycle involves bacteria and N2 fixation?
Nitrogen Cycle
The interactions between two species where one species is the hunted food source for the other
Predator-Prey relationship
What causes a population to level off and have logistic growth like in the graph shown below? (i.e. why can't a population just keep growing and growing?) 
Limiting Factors
Give at least 2 examples of ABIOTIC limiting factors
drought, severe winter, natural disaster, virus-caused diseases, etc.
An animal population decreases from 800 individuals to 600 individuals. What are 2 biotic factor that could have caused this decrease?
Disease and predation
Growth that slows due to limited resources; S- curve graph; carrying capacity
Logistic Growth
What is a process in the water cycle that releases water into the atmosphere from PLANTS?
Transpiration
Begins in essentially lifeless areas, such as regions in which there is no soil or where the soil is incapable of sustaining life.
Primary Succession
What is the carrying capacity? 
about 250
In a forest ecosystem, which of the following is the best example of a limiting factor for a rabbit population?
a. the robin (bird) population
b. amount of grass/flowers available
c. the amount of sunlight
d. rabbits have no limiting factors
b. amount of grass/flowers available
Why does the hare population decrease?

There are more predators at that time, so they are getting eaten more
The variety of living species on Earth, including plants, animals, bacteria, and fungi.
Biodiversity
If many trees are removed from a forest, what is the most immediate effect on the carbon cycle in that forest?
increase in the rates of atmospheric carbon dioxide
When is carrying capacity reached? Be specific.
Birth equals Death
Immigration equals Emigration
Which of the following might cause the carrying capacity of this rabbit population to DECREASE?
a. increase in food for a few years
b. fewer predators
c. harsh winters for a few years
d. more resources available in the ecosystem

c. harsh winters for a few years
Based on this graph, what is the limiting factor for the hare population? 
the lynx population
(just like what we saw with the ecological pyramids, there are more primary consumers like the hare than there are top predators like the lynx)
What is the limiting factor for the lynx? 
The hare
What is an invasive species. Be thorough w/ example.
Invasive species are non-native to an area, they damage ecosystems by affect native species populations.

Which letter in the image represents respiration?
X
Data on the immigration and emigration of a fish species would be most helpful in determining which of the following?
A. biological magnification
B. predator-prey relationships
C.interspecies competition
D. population of the species
D. population of the species
