Biodiversity
How many levels of biodiversity are there?
3
Money generated by recreation is known as a ____________ ecosystem service
cultural
________ natural disturbances occur with regular frequency
periodic
Organisms that are better adapted to their environment will survive and pass on their genes, this is known as __________
natural selection
The ______________ appears last in ecological succession, after soil has been deepened and enriched.
climax community
The number of different habitats available in a given area is known as ___________ diversity
ecosystem diversity
Lumber for construction is known as a ___________ ecosystem service
provisioning
Some individuals have __________ that give them a wider range of tolerance than the baseline for a species.
adaptations
T/F
The longer the lifespan of the organism, the slower the rate of evolution
true
____________ natural disturbances occur with irregular frequency (hurricanes, drought, fires)
episodic
___________ diversity includes the balance or evenness of all populations in the ecosystem.
species
Trees in a forest can sequester ___________ through photosynthesis, which helps reduce the rate of climate change
carbon dioxide
The range where organisms survive, grow, and reproduce is known as ____________
optimal range
_____________ starts from bare rock in an area with no previous soil.
primary succession
_________ can grow directly on rock.
moss
lichen
Species ___________ is the total number of different species found in an ecosystem.
richness
Wetland plant roots can filter _________, leaning to cleaner groundwater and making it cheaper than the alternative of wastewater treatment.
pollutants
The _____________ is the range where organisms will die (due to suffocation, lack of food, thermal shock)
zone of intolerance
_____________ starts from already established soil in an area where a disturbance cleared out the majority of plant life.
secondary succession
__________ factors such as temperature, pH, salinity affect the ecological range of tolerance
abiotic
_____________ events reduce genetic diversity.
bottleneck
There is an ____________ relationship between island distance from mainland and species richness
inverse
(further away from mainland, less species diversity)
The _________________ is the range where organisms survive, but experience infertility, lack of growth, decreased activity etc.
zone of physiological stress
True/False
Maples and oaks are examples of mid-successional species.
false
____________ natural disturbances occur with no regular frequency.
random
