Population Ecology
Population Ecology
100
Individual, living thing
What is organism
100
Capture energy from the sun or the environment and converts it to "food", also can be known as the "producer"
What is autotrophs
100
The regular pattern of changes in the types of species in a community
What is succession
100
The area in which a population lives - its range
What is geographic distribution
100
Number of individuals in an area
What is population density
200
Always composed of same-species organisms
What is population
200
Must get their energy from other living things, also known as "consumers"
What is heterotrophs
200
End result of changes, if left undisturbed
What is climax community
200
Measures how a population grows over time
What is population growth
200
The number of organisms an environment can support
What is carrying capacity
300
Large area that has a particular climate, with certain species of plants and animals living there
What is biome
300
Shows more complex interactions understanding that organisms don't just eat one type of food
What is food web
300
New land is created and succession begins
What is primary succession
300
As resources become less available, growth slows or stops - S shaped
What is logistic growth
300
Organisms reproduce at a constant rate
What is exponential growth
400
The part of the earth that supports life
What is biosphere
400
Each step in a chain or web
What is trophic level
400
Succession in aquatic ecosystems
What is eutrophication
400
Natural disasters, some human activity and unusual weather are examples of this
What is density-independent factors
400
Any factor in an organism's environment that causes population growth to decrease
What is limiting factor
500
The community plus the physical factors in an area
What is ecosystem
500
Shows how energy (in measurable amounts) passes from one type of organism to another
What is ecological pyramids
500
Destructive use of land results in the formation of desert conditions
What is desertification
500
J-shaped curve
What is exponential growth
500
How populations change in any given area
What is population dynamics
