Biodiversity Review

The number of different species of plants and animals in area refers to what vocabulary word?

• Speciation
• Biodiversity
• Extinct
• Ecosystem

an evolutionary event in which a significant percentage of a population or species is killed or otherwise prevented from reproducing

• population bottleneck

• mutation

• genetic resistance

• differential reproduction

• genetic recombination

all individuals of the same species occupying the same area is

• an ecosystem

• a population

• a community

• a biome

• a biosphere

Change in allele frequency in a population due to random sampling is

• Genetic drift

• Co-evolution

• Artificial selection

• Genetic resistance

• None of these

Which is the best example of a population bottleneck?

• A tsunami wipes out the entire population of plants

• A new food source is available to a population of cats

• A wild fire kills off a significant portion of a deer population

• A volcano causes the extinction of a small mammal species

• Climate change causes the local population of birds to migrate elsewhere

A bird population has an adaptation of a curved beak to feed on the nectar inside of a curved flower. This is

• Competition

• Genetic resistance

• Species richness

• Co-evolution

• Reproductive isolation

all the genotypes within a population

• ecosystem service

• gene pool

• phenotype

• ecological niche

• reproductive isolation

A small sample of the population is relocated to a new spot and starts a new population with genetics different from the original population

• Doppler effect

• Founder effect

• Reverse population bottleneck

• Artificial selection

• Mass extinction

Describes differences in DNA among individuals of a population or species.

• Subspecies

• Genetic Isolation

• Species Diversity

• Genetic Diversity

The trait that makes a living thing better able to survive is called

• an adaptation.

• a clone.

• a vestigial organ.

• competition.
