Population Growth
The number of individuals per unit area is called. . . .
population density
The range of external conditions within which a species can survive and reproduce
Tolerance
Disease spreads easily when a population is crowded together. This is an example of a density-dependent factor
True
Resources, when used, that are unable to replenish or may take millions of years to replenish.
Nonrenewable resources
The name of an earthquake on Mars
Marsquake
The maximum number of individuals a habitat can support over time
Carrying capacity
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
Commensalism symbiosis is when 2 organisms benefit in a relationship with one another
False
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
When bananas are subjected to ultraviolet light they glow. . . . (what color?)
Blue
If growth rate is > 0 its population will
increase
A type of symbiosis where one organisms benefits and the other organism does not benefit and is unharmed
Commensalism
A keystone species is not a necessary component of a healthy ecosystem
False
The amount of land, water, and energy (resources) that are needed for the way a person lives is called their. . .
ecological footprint

badgers,
walruses,

Typically, the higher a region's biodiversity results in an increased ability to recover from changes in the environment. This is called. . . .
resilience
Ocean acidification occurs because carbon dioxide combines with water to form carbonic acid
True
A human altered biome is called. . . .

The #1 most common allergy in humans is. . .
Shellfish
A type of population growth that assumes resources are infinite
Exponential growth
Ecosystem services
All of the following are density-independent limiting factors:
Natural disaster Temperature Forest fire
Competition
False
Competition is not a density-independent factor
The concentration of pollutants increase as the number of organisms at a Trophic level decreases
Biomagnification
