Biodiversity, aka biological diversity, usually refers to
the same species in a general location
the variety of life in the world or in a particular habitat or ecosystem
the number of animal species in a given area
the number of plant species in a given area
Succession that occurs in areas that previously didn't support life, such as on rocks or ice
tangential succession
primary succession
secondary succession
quaternary succession
A common type of succession that occurs where an event such as a forest fire has occurred
common succession
primary succession
secondary succession
Quaternary succession
Which habitat exhibits the greatest biodiversity? Species Richness? Species Evenness?
A habitat with 15 different species with about 300 individuals each
A habitat with 10 different species with about 75 individuals each
A habitat with 4 different species with about 150 individuals each
A habitat with only one species with about 2000 individual
Why is biodiversity important?
Because all species depend on each other to survive, so if one becomes extinct another species that relies on it could go extinct as well
Because it’s better to have only one variation of each species.
Because it better to only have a few species on Earth.
Honestly, I have no idea what biodiversity is!
How does the theory of Island Biogeography impact biodiversity?
Where are many critical biodiversity hotspots located?
islands
tropical rain forests
coastal areas
artic tundra
In what way are humans most impacting the biodiversity of ecosystems around the world?
a. We are putting too many organisms in zoos or keeping them as pets
b. We are increasing biodiversity by breeding new species
c. We are destroying the habitats of a large number of species
d. Recreational hunting
What is latitudinal gradient?
A global pattern of species richness that changes with latitude
A specific area on the globe
Where all species originate from
Describes taxonomic groups
A sustainable ecosystem typically has high biodiversity.
True
False
(a) are the first organisms to colonize an area and begin the process of ecological succession.
What is the main difference between primary and secondary ecological succession?
Primary begins WITHOUT soil; Secondary begins WITH soil
Primary is the first state and secondary is the second stage
Primary builds plant community; secondary builds animal community.
Primary begins WITH soil; Secondary begins WITHOUT soil
Which natural occurrence describes an incident that may lead to a primary succession?
Glaciers melt and leave exposed rock
Plants die from drought and decompose
Land is bulldozed and soil remains
A volcanic eruption
What is an increase of biodiversity over time, after a natural or man made disturbance?
ecological recession
climax recession
ecological succession
climax succession
Which anthropogenic disturbance that could bring about a secondary succession?
Bonfire in the Forest
Hurricanes
Land Clearing for New Housing Development
Tornadoes
What is the term that describes a steady and stable community?
peak community
turf community
climax community
disturbed community
Which succession reaches a climax community fastest?
Primary or Secondary Succession?
Why?
