100
the process by which traits that improve an organisms chances for survival and reproduction are passed on more frequently to future generations than those that do not
What is Natural selection
100
What role does the environment play in an organisms survival and reproduction
it can affect an animals quality of life and ability to survive
100
How do species interact in nature
They prey on one another for food
100
Animals eat plants and other animals for energy and nutrients
How do energy and nutrients move through communities?
200
Changes in DNA
What is Mutation
200
How are a gene pool and biological evolution related?
Biological evolution is a change in a populations gene pool over time. A gene pool includes all the genes present in a population
200
What is the relationship in which neither participant is harmed
Mutualism and commensalism
200
why are plants considered primary producers
Plants capture energy from the sun through photosynthesis and make it available to other organisms when the plants are eaten
300
A heritable trait that increases an individuals fitness
What is Adaptation
300
How does artificial selection provide evidence for evolution by natural selection
Artificial selection shows how selection works. Breeding for desired traits can increase their occurrence in populations. Humans decide which traits become more common, while in natural selection the environment affects which traits are selected
300
What is symbiosis
A long-lasting and physically close relationship that benefits at least one organism
300
What are autotrophs
Organisms that are also known as primary producers; where they capture energy from the sun and store it
400
process by which new species are generated
What is Speciation
400
What is mass extinction
Events of staggering proportion that has killed off huge numbers of species at once
400
What causes cycles in population size
Predation
400
What are heterotrophs
Organisms that rely on other organisms for energy and nutrients, that are also known as consumers
500
disappearance of a species from earth
What is extinction
500
What is survival of the fittest
An individual with high fitness, such as our striped fish, producers more offspring and therefore passes on its genes more frequently than an individual with low fitness
