Question 0

Realized niche

Answer 0

The portion of its fundamental niche that is actually filled, or realized

Question 1

primary succession

Answer 1

Follows a disturbance so severe that no vegetation or soul life remains from the community that occupied the site

Question 2

Resource partitioning

Answer 2

The species partition, or divide, the resource they use in common by specializing in different ways.

Question 3

Symbiosis

Answer 3

Physically close association

Question 4

Trophic cascade

Answer 4

Predators at high trophic levels can indirectly promote populations of organisms at low trophic levels by keeping species at intermediate trophic levels in check, a phenomenon ecologist would refer to this

Question 5

Resistance

Answer 5

A community that resists change and remains stable despite disturbance.

Question 6

Resilience

Answer 6

There is changes in response to disturbance but later returns to its original state

Question 7

Succession

Answer 7

When the disturbance is severe enough to eliminate all or most of the species in a community, the affected site will undergo a somewhat predictable series of changes

Question 8

Secondary succession

Answer 8

Begins when a disturbance dramatically alter an existing community but does not destroy all living things or all organic matter in the soil.

Question 9

Restoration ecology

Answer 9

The practice of ecological restoration

Question 10

Temperate deciduous forest

Answer 10

Dominates the landscape around the central and southern Great Lakes us characterized by broad-leafed trees that are deciduous, meaning that they lose their leaves each fall and remain dormant during winter, when hard freezes would endanger leaves

Question 11

Temperate grass lands

Answer 11

Westward from the Great Lakes. Temperate grasslands occur where temperature differences between winter and summer become more extreme and rainfall diminishes.

Question 12

Tropical rainforest

Answer 12

Found in Central America, South America, Southeast Asia, west Africa, and other tropical regions and is characterized by year-round rain and uniformly warm temperature.

Question 13

Temperate rainforest

Answer 13

Coastal Pacific Northwest region, heavy rainfall.

Question 14

Tropical dry forest

Answer 14

Tropical areas that are warm year-round but where rainfall is lower overall and highly seasonal…. A biome widespread in India, Africa, South America and northern Australia. Also known as a tropical deciduous forest

Question 15

Savanna

Answer 15

Drier tropical regions, tropical grasslands interspersed with clusters of acacias or other trees.

Question 16

Tundra

Answer 16

Occurs at very high latitudes along the northern edges of Russia, Canada, and Scandinavia.

Question 17

Trophic levels

Answer 17

Rank in the feeding hierarchy of a food chain. Organisms at higher trophic levels consume those at lower trophic levels.
