What two factors make up a Diversity Index?
Species Richness, Species Evenness

What is biological evolution and name a mechanism for biologic evolution?

The process whereby the earth’s life changes over time through changes in genes of populations of organisms. One mechanism is natural selection.

100
give an example of a biome
forests, desserts, etc.
100
What is resource partitioning
It is when species compete for similarly scarce resources.
100

What is carrying capacity

the number of people, other living organisms, or crops that a region can support without environmental degradation

200
What is functional Diversity?
functional diversity is the biological and chemical processes such as energy flow and matter recycling needed for the survival of species, communities, and ecosystems.
200
What is natural selection and give an example.
where individuals with certain traits are more likely to survive and reproduce. an example would be moth coloration
200
How do humans affect biodiversity--give 2 examples. Can humans ever INCREASE biodiversity?
Habitat Destruction & Hunting, genetic diversity, species transfer,
200
What is the difference between an adaptation and an evolution?
Adaptation generally refers to change that leads organisms to be suited to their local circumstances in some way, while evolution typically refers to changes in genes.
200

Name one method of estimating the number of species in an area.

Find how many exist in a small block by tagging and multiply it out or use the capture and re capture method

300
What is the difference between a community and a population?
community- includes more than one species
300
Describe the process of Speciation.
Different selective pressures lead to different species over thousands of years.
300
What are two classifications of biomes and give examples of those biomes.
terrestial and aquatic, and these include the types of biomes known as deserts, forests, grasslands, savannas, tundra, and freshwater environments
300
Name 4 of the 5 ways species interact with each other.
Introspective Competition, Predation, Parasitism, Mutualism, Commensalism.
300
In order to determine snail populations, 340 snails were captured, tagged, and released. Later, 420 snails were captured. Of the 420 snails, 16 were already marked. What is the size of the snail population?
8925
400

What does biodiversity indicate about an ecosystem? Why?

High DI= stable, sustainable ecosystem

400
Differentiate geographic isolation and reproductive isolation.
Geographic- land mass; reproductive- cannot interbreed anymore
400
What is an indicator species?
Species that serve as early warnings that a community or ecosystem is being degraded.
400
What is mutualism and give an example
the interaction that benefits both species. an example would be birds that ride on the backs of large animals
400
Name two examples of Evolution by Random Processes
Mutation, genetic drift, bottleneck effect, founder effect
500

Distinguish between keystone and foundation species. Name one of each!

Discretion.

500
What is background extinction? How does this differ from mass extinction? How many mass extinctions have we had?
-we’re in the 6th!
500
How long will it take the following population to double? Initial population: 60,000 birds. 3,000 die, and 6,000 are born each year. NO CALCULATORS
14 years
500
Name four of the six ways that prey have developed to stay alive from predators.
Camouflage, Chemical, warning collaboration, mimicry, deceptive looks, deceptive behavior.
