Succession
Trophic Levels
Species Roles
Biodiversity
Random
100
This would occur after a glacier recedes, exposing bare rock.
Primary succession
100
The organisms at the bottom of a trophic pyramid.
Producers
100
An species that causes ecological or economic harm in a new environment where it is not native.
Invasive species
100
The definition of biodiversity
Variety of life
100
Which biome has the most constant conditions?
Tropical Rainforest
200
This would occur after a forest fire.
Secondary succession
200
This trophic level has the most energy
The first one (producers)
200
Species that have become so rare they may become extinct.
Endangered species
200
An important species that, if removed, would set off a chain of events that turns the structure and biodiversity of its habitat into something very different.
Keystone species
200
An ecological relationship in which one organism benefits and the other organism is unaffected?
Commensalism
300
The reason why secondary succession occurs faster than primary succession.
There is already soil and nutrients present.
300
Organisms at the second trophic level.
Primary consumers
300
A plant or animal that is native and restricted to a specific geographic area.
Endemic Species
300
What is an ecosystem service? What is an example of an ecosystem service?
An ecosystem service is a resource that was given to humans from the environment. An example would be food, water cycle, climate regulation; etc.
300
The net primary productivity of an ecosystem is 2 kg C/m2/year, and the energy needed by the producers for their own respiration is 5 kg C/m2/year. The gross primary productivity of such an ecosystem would be?
7 kg C/m2/year
400
A species that is the first to colonize an area or first to repopulate an area.
Pioneer species
400
Where the remaining 90% of energy goes if only 10% is transferred between trophic levels.
It is used for growth, reproduction, and living, or is lost as heat.
400
A reason why a species might be intentionally introduced in a new area.
Pest control, hunting/fishing (recreation), new food source
400
The reason why community 1 would be considered more biodiverse.
It has a more even relative species abundance.
400
During which process is light energy converted from carbon dioxide and water into glucose and oxygen?
Photosynthesis
500
The "endpoint" of succession.
A climax community
500
Assuming that a population of deer had an energy content of 4500 kcal, the energy content that we would predict in the third trophic level would be what?
450 kCal
500
The three things an non-native species must do in order to be considered invasive.
Adapt quickly, spread quickly, cause harm
500
What are 3 types of measurement of biodiversity?
Species Richness, Species Evenness, Island Biogeography, OR Genetic diversity
500
What the acronym HIPPCO stands for and represents.
HIPPCO represents human impact on biodiversity. It stands for:
H: Habitat destruction
I: Invasive species
P: Pollution
P: Population
C: Climate change
O: Overexploitation
