100

This is the name for an ecological relationship where two different species live in close association with one another

Symbiosis

100

When 2 species need the same limited resource resource, the result is this

Competition

100

An organism's role in the ecosystem is defined as this

Niche

100

The amount of plant material produced in a given plot of land

Productivity

200

This is an ecological relationship where one organism kills another for food

Predation

200

When two species are in direct competition and share the same niche this will be the eventual result

Competitive Exclusion

200

All of the resources opportunities an organism could potentially occupy 

Fundamental Niche

200

An apex predator that controls herbivore populations and helps top regulate the ecosystem

Keystone Species

300

This is an ecological relationship where one organism lives in or on another organism and takes nutrients from it bt does not kill it

Parasitism

300

When 2 or more species are eat the same thing, but in different places they are reducing this type of relationship

Competition

300

The niche a species actually occupies as a result of competition

Realized Niche

300

Sea Stars, Sea Otters, Starfish, and Wolves are all examples of this

Keystone Speces

400

This is an ecological relationship where two organisms benefit each other

Mutualism

400

Competition can be reduced by this type of ecological relationship

Predation

400

Slight variations in the niche of two different organisms to reduce the effect of competition

Niche Partitioning

400

The study of the Cape May Warbler helped scientists to understand this ecological concept

Niche Partitioning

500

This is an ecological relationship where one organism benefits and the other is uneffected

Commensalism

500

Because Predation can reduce competition, it also has the effect of increasing this ecological aspect

Biodiversity

500

If two species are unable to partition their niche and they occupy the same exact niche, this can be the result

Competitive Exclusion

500

Higher biodiversity in a plant plot is associated with higher levels of these two ecological components

productivity and drought tolerance
