What do we call the dotted line labeled "D"

Carrying Capacity
Something that limits the species of a population in an ecosystem.
limiting factor
What is the difference between biotic and abiotic factors?
Biotic factors are living organisms and Abiotic factors are non-living factors in an ecosystem.
Define biotic factors
Which biome has very little rainfall, making water a major limiting factor?
Desert
In an ecosystem, what is the carrying capacity?
the maximum number of individuals of a population that the environment can support is the...
Disease (bacteria), food availability, predators, etc.
In an ecosystem, what can cause the decrease of a population?
Predation, lack of food supply/habitat, deforestation
Define Abiotic Factors
The non-living parts of an ecosystem.
Which biome has four seasons and trees that lose their leaves?
Decidious Forest
Identify a possible limiting factor that can cause the mouse population to reach its carrying capacity. 
Limiting Factors: predators, habitat, competition for resources
Give at least 2 examples of ABIOTIC limiting factors
drought, severe winter, natural disaster, virus-caused diseases, etc.
Limiting factors determine the carrying capacity of an ecosystem.
Define Limiting Factors.
Anything that slows or stops a population from growing.
In a grassland, what abiotic factor often limits tree growth?
Rainfall
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
What happens to a population when it reaches the carrying capacity?
It stays the same size or levels off.
Define Carrying Capacity.
The maximum number of individuals an ecosystem can support
Which biome has frozen soil (permafrost) that limits plant growth?
Tundra
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
Which is the best example of a limiting factor in a desert:
a) too many trees
b) lack of water
c) too much soil
d) unlimited food
b) lack of water
Why do populations in nature rarely stay the exact same size for long?
Because resources and conditions constantly change.
Define Ecosystem
All the biotic and abiotic things in an area.
What's the difference between a coniferous forest and a decidious forest?
Decidious forests have trees that drop their leaves in the fall and stay bare in the winder, coniferous forests don't.
