What is Intraspecific competition?
What is same species competition
Type of mimicry where an animal blends into its surroundings to avoid detection
What is camouflage
Change in the genetic material of an organism
What is mutation
Which country is the richest is the world
What is the USA
What is the most biodiverse biome in the world?
What is tropical rainforest
This factor affecting ecosystems is non-living.
What is abiotic?
___________ is an adaptation that allows prey to survive by blending in with the environment
what is camouflage
Population leaving an area
What is emmigration?
Maximum number of organisms that can be supported in a given environment.
What is carrying capacity?
What is the measure of the value of all consumer & government spending, exports, and manufacturing.
GDP (gross domestic product)
Variety of living organisms in an ecosystem
What is biodiversity?
An organisms role & position in its environment
What is Niche
This occurs when one organism benefits from living and feeding on another organism.
What is parasitism?
This is a relationship where two species live in close association
What is symbiosis
Type of selection that selects against the extremes
What is stabilizing selection
What shape of a population pyramid would come from very low birth rate but a large number of middle aged humans?
What is a diamond
Term for when no organisms of a population exist anymore
What is extinction
An organism's "home" in an ecosystem
What is Habitat
_________ is a relationship between organisms where one species benefits and the other is neither harmed nor helped
What is commensalism
What kind of growth curve would there be within a population if there are few individuals with an abundance of resources?
What is exponential
What is the number of individuals living in a defined area at a given time?
What is population density
Population entering an area or country
What is immigration
This is determined by the maximum number of offspring a species can produce
What is Reproductive potential?
What type of succession involves colonizing bare rock?
What is primary succession.
These organisms photosynthesize and are part of any food web or chain
What are the producers?
The peppered moth populations changing because of a change in bark color is an example of?
What is natural selection (specifically, directional selection)
This growth shows a j-shaped curve where populations can grow faster and faster
What is exponential growth?
What type of birth rate is generally found in less developed countries
A community of living organisms and their physical environment, interacting as a unit
What is an ecosystem
What is pioneer
In this type of relationship both organisms benefit from the interaction
What is mutualism
This type of growth curve is around the carrying capacity and has minor ups and downs around the carrying capacity.
What is logistic growth
Type of selection that leads to two distinct species
Disruptive or Diversifying selection
True
Features or traits that help a living thing survive in its environment
What are adaptations
What is a climax ecosystem.
