Brown Biology Chapter 5, 6 & 7

Population Growth

100

The number of individuals per unit area is called. . . .

population density

200

The maximum number of individuals a habitat can support over time 

Carrying capacity

300

If growth rate is > 0 its population will

increase

400

If a portion of a population emigrates, the overall population will. . .

decline 

500

A type of population growth that assumes resources are infinite

Exponential growth

Habitats and Niches

100

The range of external conditions within which a species can survive and reproduce

Tolerance

200

3 bird species live in a tree, but occupy and feed from different locations in the tree.  Each bird lives in its own specific . . . . .

niche

300

A type of symbiosis where one organisms benefits and the other organism does not benefit and is unharmed

Commensalism

400

Typically, the higher a region's biodiversity results in an increased ability to recover from changes in the environment.  This is called. . . . 

resilience

500

Each species in a habitat provide important functions such as reducing soil erosion, recycling water, cycling nutrients, etc.  These functions are called. . . .

Ecosystem services

True/False

100

Disease spreads easily when a population is crowded together.  This is an example of a density-dependent factor

True

200

Commensalism symbiosis is when 2 organisms benefit in a relationship with one another 

False

300

A keystone species is not a necessary component of a healthy ecosystem

False

400

Ocean acidification occurs because carbon dioxide combines with water to form carbonic acid

True

500

All of the following are density-independent limiting factors:

Natural disaster         Temperature          Forest fire     

Competition

False

Competition is not a density-independent factor

Ecological Footprints

100

Resources, when used, that are unable to replenish or may take millions of years to replenish.

Nonrenewable resources

200

A threat to biodiversity that occurs when large habitats are broken into smaller, isolated habitats (example: building a road, construction of houses/stores, etc)

Habitat Fragmentation

300

The amount of land, water, and energy (resources) that are needed for the way a person lives is called their. . . 

ecological footprint

400

A human altered biome is called. . . .

an anthrome

500

The concentration of pollutants increase as the number of organisms at a Trophic level decreases

Biomagnification

Miscellaneous

100

The name of an earthquake on Mars

Marsquake

200

When bananas are subjected to ultraviolet light they glow. . . . (what color?)

Blue

300

Chewbacca's sounds- in Star Wars- are a mixture of which animals? 

(get at least 2 to earn the points)

badgers, 

walruses, 

lions, and 

bears

400

The #1 most common allergy in humans is. . . 

Shellfish

500

This is the smallest country in the world.

Vatican City- 0.44 square km
