Diversity
Luck of the Draw
100
Eat and avoid being eaten long enough to reproduce.
What do individual organisms strive for?
100
A group of individuals that are available to each other for reproduction.
What is a population?
100
The general name that we give to the all the factors that limit a populations carrying capacity.
What is Environmental Resistance?
100
Small differences in the genetic makeup of individuals in a species.
What is Genetic Diversity?
100
Limiting factors that come from outside the population.
What is Extrinsic limiting factors?
200
Slightly different combinations of genetic traits make some individuals more competitive.
What gives some individuals a selective advantage over other organisms?
200
The study of how populations rise and fall.
What is Population Dynamics?
200
These come from outside the population. Examples include chemical nutrients, the light level, water.
What are aboiotic limiting factors?
200
The variety of species (populations) in a community.
What is Species Diversity?
200
To assure that the number of births exceed the number of deaths.
What is the purpose of Reproductive Strategies?
300
When individuals have a selective advantage and are able to breed more offspring.
What is Differential Reproduction?
300
...the number of offspring, their average survival rate, and how early and often they reproduce?
What factors influence the Biotic Potential, or the maximum growth rate of a population?
300
Living things that limit a populations carrying capacity. Examples include the food supply, predators, and disease.
What are Biotic Limiting Factors?
300
The variety of lakes, deserts, grasslands, streams and other biological communities.
What is Ecological Diversity?
300
This reproductive strategy is used by organisms with high growth rates.
What is r-selection?
400
A new species develops due to geographic isolation from their ancestral species.
What is Allopatic speciation?
400
Type r selection.
What reproductive strategy has masses of offspring in one reproductive shot?
400
This intrinsic limiting factor keeps individuals in a population from living too close together.
What is Territoriality?
400
When two or more species evolve to take advantage of each other.
What is Coevolution?
400
Limiting factors that come from within the population.
What is Intrinsic Limiting Factors?
500
New species develop due to seasonal, habitat, or behavioral isolation from their ancestral species.
What is Sympatric Speciation?
500
The number of individuals in a population that can be sustained indefinitely.
What is the Carrying Capacity?
500
Population growth that severely disrupts the ecosystem.
What causes a population crash (big reduction in carrying capacity?
500
It makes populations and communities more adaptable and resilient.
Why is diversity important?
500
Populations that try to maximize the chance of surviving at or near their carrying capacity.
