there
2 different species mating and creating brand new in between species
hydroization
what effect does genetic drift have of gene pools
deceases variation
The study of living organisms and their interaction with each other in the environment
ecology
animal that eats both plants and meats
omnivore/comsumer
The % of NRG that moves from 1 trophic level to another
10%
change in allele frequency in a population
genetic drift
what effect does gene flow have on gene pools
Increasing variation
Living things in the ecosystem
Biotic
Organisms that obtain NRG from dead plants and animal matter
detravore/decomposer
Organisms usually not involved in the food web
decomposer
when part of a population finds a new habitat and colonizes it
founder effect
when natural selection favors one extreme
directional
non living things in the ecosystem
abiotic
Organisms that obtain NRG from sunlight to make their own food
Producer/autotroph
where most of all the NRG in food chains and webs come from
Sun
when 2 different populations of the same species continue to mate and share their genes
gene flow
when natural selection favors the average
Animal that only eats plants
Herbavore/consumer
Organisms that must consume energy from others
consumer/heterotrophs
The most efficient transfer of NRG is when a heterotroph eats this
A producer
the effect of a major event that courses the death of many individuals thus genetic variation is greatly decreased
bottleneck effect
when natural selection favors both extremes and less of the average is seen over time
disruptive
Animal that only eats meat
carnivore/consumer
the trophic level with the highest amount of available energy and matter
producers/bottom
What do arrows in food chains and webs represent
NRG flow
