Population Ecology
100
A group of organisms that are the same species.
What is a population?
100
This natural process in plants absorbs carbon dioxide to make sugars, thus decreasing the amount of carbon in the atmosphere.
What is photosynthesis?
100
Any organism that can produce its own food
What is an autotroph?
100
A type of relationship when one organism benefits, and the other is unaffected.
What is commensalism?
100
A growth pattern based off of unlimited resources, in which the population continues to grow without limit.
What is exponential growth?
200
A community of interacting organisms and their physical environment.
What is an ecosystem?
200
This process is the water evaporates from stomata in plants.
What is transpiration?
200
The level of consumers that eat producers.
What are primary consumers?
200
When two organisms must compete over the same food source.
What is competition?
200
A growth pattern where eventually the population reaches a limit because resources are finite.
What is logistic growth?
300
Two organisms that can reproduce to create fertile offspring.
What is species?
300
This process can carry water and other particles across land and into water sources, which can be harmful to many ecosystems.
What is runoff?
300
The flow of this is represented by the arrows pointing to consumers in a food web.
What is energy?
300
A small bird lives on and around a rhino. The small bird gets nutrition and food while the rhino gets cleaned of parasites and insects.
What is mutualism?
300
The maximum number of individuals that a geographic range can support.
What is carrying capacity?
400
Groups of populations that live together in a defined area.
What is a community?
400
The burning of these have resulted in huge increases in carbon levels in the atmosphere.
What are fossil fuels?
400
Frog and Shrew
Review the food web on the board. List all secondary consumers.
400
A small organism resides within a host and feeds off of the host's nutrients, blood, etc. while the host becomes ill and weak.
What is parasitism?
400
These factors affect population growth regardless of how big, small, or dense the population is.
What are density-independent factors?
500
A nonliving, physical component of an ecosystem.
What is abiotic?
500
The process of transforming nitrogen in the atmosphere into a usable form for plants.
What is nitrogen fixation?
500
According to this principle, the energy received at each level is only a fraction of what was harvested by the previous trophic level
What is the 10% Rule?
500
When 2 species live so closely together that they have a relationship.
What is symbiosis?
500
These factors are linked to density, and the more a population grows, the higher impact they have.
What are density-dependent factors?
