ECOL 111 Section C Questions and Answers
(100% Correct Answers) Already Graded A+
What stressors are facing marine environments Ans: Fossil fuels
producing CO2 which is absorbed by oceans
NZ threatened categories depend on Ans: pop size, trend, adopt worst
case -> very small populations, high ongoing or predicted decline
© 2026 Assignment Expert
What taxonomic group has highest proportion of threatened species
Ans: Reptiles, freshwater fish
Guru01 - Stuvia
Key Threats to Plants in NZ Ans: Exotic weeds
Pests (browsers, grazers)
Habitat destruction
Climate change
Plant collection
What are wetlands Ans: Areas where water covers the soil or is present
either at or near surface for varying periods of time during year
Key Threats to Biodiversity + Examples Ans: Land-use change -
deforestation
Exploitation - over fishing
, For Expert help and assignment handling,
2
Climate change - erosion, warming ocean (1/6 species effected)
Pollution - atmospheric deposition of N
Invasive species
What is the IUCN Red List Ans: A research method helping track trends in
biodiversity - categorise species on level of threat, shows distribution, pop
size, indicate health of biodiversity
© 2026 Assignment Expert
why does biodiversity matter Ans: ecosystem stability, biogeochemical
cycles, food, key resources for humans, inspiration and quality of life
Guru01 - Stuvia
How does saturated community effect niche Ans: Denser environment
resulting in more niche overlap and increased competition
Metapopulation definition Ans: Overall population divided into
subpopulations by the patchiness of environment
How does productivity influence species richness Ans: Primary
productivity measure rate of plant biomass, more biomass = more plant
biodiversity
Types of parasites Ans: Microparasites - infection resulting in
multiplication within host (virus)Macroparasites - infection may be
repeated and reproduction happen in host (worms)
How does size and remoteness impact island biodiversity Ans: Smaller
islands have higher extinction levels, bigger islands have higher nutrients,
islands closer to mainland have higher immigration levels and higher
species richness
