Natural Selection
Question | Answer |
---|---|
a characteristic or change that allows an organism to blend in or survive within their environments | adaptation |
an adaptation that allows an organism to blend in with its surroundings | camouflage |
resemblance of one species to another species | mimicry |
process by which populations of organisms with variations that help them survive in their environments live longer, compete better, and reproduce more than those that do not have the variations. | natural sellection |
slight difference in an inherited trait of individual members of a species | variation |
the actions of an animal allow it to survive | behavioral adaptation |
shape, color, and other physical characteristics that allow an organisms to survive in its environment | structural adaptation |
How does mater energy move in an ecosystem? | in one direction |
How do materials such as carbon, nitrogen, and water move through an ecosystem? | in a cycle |
the What is the first organism consumed in food web? | producer |
non-living factors like soil, water, climate | abiotic factors |
living organisms like plants, animals, and bacteria | biotic factors |
Darwin concluded that organisms on the Galapagos Island | had different variations |
Differences between members of the same species are called | variations |
species is a group of similar organisms that | can mate and fertile offspring |
structures that related species have inherited from a common ancestor | homologous structures |
humans and bats are found to have a common ancestors the homologous structures to arms | bats' wings |
natural selection leads to evolution | helpful variations add up among the surviving members in a population |
two organisms look very very similar during their early stages of development is evidence | common ancestor |
fossils form from | dead organisms becomes buried in sediment |
a slight change in a rabbit's ability to hear is predators better to help it survive | adaptation |
what are fossils | preserved remains or traces of organisms that lived in the past |
natural selection is affected by these traits that are different in members of the same species | variations |
states that species evolve slowly over a relatively slow time | evolution |
organisms that usually mate and produce fertile offspring | species |
a new species evolves from an existing species | natural selection |
living factors | biotic |
non-living factors | abiotic |
actions or behaviors that allow an organism to survive | behavioral adaptation |
energy flows in | one direction |
hibernation is an example | behavioral adaptation |
allows an organism to blend in with their surroundings | camouflage |
color, shape, and size are physical characteristics that allow an organism to survive | structural adaptation |
when a species resembles another species to survive as a defense | mimicry |
climate, soil, sand , water, sunlight | abiotic factors |
all the populations of different species that live in the same area at the same time | community |
the struggle in a community for resources such as food and shelter | competition |
what a species does to survive | niche |
place within an ecosystem where an organism lives | habitat |
all of the organisms that live in an area at the same time with living and non-living parts of the environment | ecosystem |
all the organisms of the same species that live in the same area at the same time | population |
consumers that eat other consumers | carnivores |
consumers that eat producers | herbivores |
consumers that eat dead organisms | detritivores |
consumer that eat producers and consumers | omnivore |
made up of all the fossils ever on Earth | fossil record |
preserved evidence pf the activity of an organisms | trace fossil |
