What is the first species to colonize a new habitat?
Pioneer Species
An orderly replacement of populations in an area that has not previously supported life.
Primary Succession
The stable ecosystem that develops due to succession
Climax Community
Barren Rock Aspens Perennial Grasses Lichens Spruces What process is illustrated by the diagram?
Primary Succession
According to the diagram which of the following represents a seral community? Barren Rock Aspens Perennial Grasses Lichens Spruces
Aspens
True or False: The Tundra is dominated by coniferous trees
False
The biome we live in is?
Deciduous Forest
A large group of ecosystems identified by the same type of climax community is called?
Biome
This biome is dominated by cone bearing evergreen trees, it lies south of the tundra.
Coniferous Forest
The biome that is located on the west coast of the U.S., dominated by large trees or shrubs.
Woodland or Shrubland
What are the two types of aquatic biomes? (hint: two types of water)
Freshwater & Saltwater or Marine
What are the 2 types of freshwater ecosystems?
Moving water and Standing water
What are the 3 types of stream habitats?
Riffle, Run, Pool
A place where salt water and fresh water meet.
Estuary
What are the 3 zones of a lake?
Littoral, Limnetic, Profundal
The term used to describe the oxygen content of water.
Dissolved Oxygen (DO)
The number of species in an area is called?
Population Density
Limiting factors (i.e. food, water, etc.) whose effects are dependent on the population density.
Density- dependent factors
Limiting factors whose effects are not influenced by population density are called?
Density- independent factors
What is the statistical/scientific study of populations called?
Demography.
What is the movement of species into a population called?
Immigration
Competition is a type of factor that can control population size what is the name of that factor.
Limiting Factor
How do you determine if a population is growing or not?
Take the birth rate minus the death rate.
What is it called when organisms move from one population to another?
Emigration
This shows the population of a country broken down by gender and age group.
Age-Structure Diagrams
Exponential growth forms what type of curve.
J
To determine if a population is growing or not what would you have to do.
Take the birth rate – death rate.
Factors such as food, space, and water that limits the size of a population is know as.
Limiting factors
As a population approaches it carrying capacity its graph forms what shape.
S
The number of organisms an environment can handle is called.
Carrying Capacity
