Levels of Ecological organization
This is the name for a group of individuals that interbreed and produce fertile offspring.
What is a species?
This is the name for the population distribution type where individuals are arranged without a particular pattern.
What is random?
This is the sequence of DNA that codes for a particular trait.
What is a gene?
An organism's this describes its use of resources and its functional role in a community.
What is a niche?
What is equilibrium?
This is the lowest level of ecological organization, and it looks at the relationship between an organism and its physical environment
What is individual?
This most widely seen distribution has the organisms arrange themselves by the resources available.
What is clumped distribution?
What is artificial selection?
Also called autotrophs, organisms that capture energy from the sun or other chemicals are called these.
What are primary producers?
When a disturbance is so severe that no vegetation or soil life remains, this occurs.
What is primary succession?
This level of organization refers to a group of different species that all interact with one another.
What is a community?
Floods and other natural disasters are this kind of limiting factor.
What is a density-independent factor?
This is the process by which new species are generated.
What is speciation?
Organisms with wide tolerance ranges are called this.
Fire, logging, or farming can often start this process - which doesn't take as long as it's first type.
What is secondary succession?
What is an ecosystem?
What is a type 3 curve?
This describes how reproductively successful an organism is in its environment.
What is fitness?
This is the name for an organism's rank in a feeding hierarchy.
What is a trophic level?
Zebra mussels, cats, and honeybees are all examples of these.
What are invasive species?
This is the name for the study of how organisms interact with each other.
What is ecology?
This term refers to the largest population that an environment can sustainably support.
What is carrying capacity?
Unlike mutations, migrations, and natural selection, this type of mechanism of biological evolution occurs when a random event happens that changes the gene pool.
If an organism benefits from an interaction, while the other organism is not affected in any way, it is an example of this.
What is commensalism?
This mutualistic relationship between algae and fungi is a particularly successful pioneer species.
What is lichen?
