Miscellaneous
100

This level of ecological organization includes both abiotic and biotic factors

Ecosystem

100

This type of symbiotic relationship benefits both organisms

Mutualism

100

These structures are similar in function but different in appearance (do not share a common ancestor)

Analogous structures

100

This mechanisms involves changes in DNA that can be neutral, beneficial, or harmful.

Mutations

100

This term is used to describe organisms fighting to obtain limited resources before other organisms do for survival.

Competition

200

This type of symbiotic relationship benefits one and harms the other

Parasitism

200

Name the for cycles of matter we discussed

Water, Carbon, Nitrogen, and Phosphorous

200

These structures were important in ancestral species but are no longer used in the currently living organism

Vestigial structures

200

This mechanism involves new genes or alleles coming into or out of a population

Gene flow

200

Term used to describe a geographic separation of species that then produces two different species?

Geographic isolation

300

An organism's role or job within its environment

Niche

300

An organism's place of living/home/location within it's environment

habitat

300

These structures do share a common ancestor, have similar anatomy, but do not have the same function

Homologous structures

300

This mechanism involves organisms choosing mates based on specific characteristics or interbreeding within a small species.

Non-random mating

300

This amount of energy is transferred between the trophic levels in a food chain

10%

400

This level of ecological organization includes areas of similar climates but not necessarily in the same area

Biome

400

When an organism evolves to look like another organism (not camouflage)

Mimicry

400

A cat leg and human arm is an example of this type of evidence of evolution

Comparative anatomy OR homologous structure

400

This mechanism involves the elimination of gene from a species by random chance

Genetic drift

400

Instead of only the strongest/fastest/smartest surviving, it's actually the organism's ability to adapt to it's environment that allows it to survive....called this term

Fitness or fit

500

A group of individuals from different species hanging out in the same area

Community

500

Name the trophic levels

Producer, primary consumer, secondary consumer, tertiary consumer, decomposer

500

Comparing DNA sequences between different species is the practice of what type of evidence of evolution

Comparative Biochemistry/Molecular Biology

500

Name the 5 mechanisms of evolution

Natural selection, gene flow, genetic drift, mutations, non-random mating

500
Giraffes used to have long, medium, and short necks...this is an example of what in a population

Variation (genetic variation...gene variation)
