Biodiveristy
What are the three stages of biodiversity? (Largest to smallest)
Ecosystem diversity, species diversity, genetic diversity
What are the four ecosystem services?
Provisioning, regulating, supporting, cultural
What are the three stages of ecological range of tolerance?
Optimal Zone: Where species thrive
Zone of Physiological Stress: Where species are taken out of the optimal zone and are stressed
Zone of Intolerance: Results in death
What is the difference between primary and secondary succession?
Primary succession occurs on bare rock while secondary succession happens when soil is already established
Describe the difference between species richness and species evenness
Species richness is the total amount of different species in an area. Species evenness is the balance of the different species in an area
Describe what a cultural ecosystem service looks like
Having a flourishing wetland ecosystem can increase tourism, allow for recreational parks, increase scientific advancements and allow for more revenue to be generated
UNIT 9 CONNECTION!: What does HIPPCO stand for?
Habitat loss/fragmentation, Invasive species, Population growth, Pollutants, Climate change, Overexploitation
How is soil formed in primary succession?
Soil is formed through the breakdown of rock from moss and lichen. Moss and lichen usually arrive through wind
Regulating
How is soil formed in secondary succession?
TRICK QUESTION: Soil is already present during primary succession, only the vegetation is destroyed.
If a forest was completely clearcut, describe what ecosystem service humans would lose (answers may vary)
Humans may lose the regulating ecosystem services as trees sequester CO2, which is a greenhouse gas
Explain the difference between pioneer species and species that appear in the climax community
Pioneer species are the first to appear and typically don't require established soil. Species that appear in the climax community are larger, need established soil, and are the last to appear
Explain each ecosystem service that come from wetlands
Provisioning: Fish, water, wood
Regulating: Storm protection
Supporting: Water cycle
Cultural: Tourism benefits
