Try a few questions
- Practice question 1
Altitude, as a factor controlling vegetation, can cause
- A.distinct vegetation zones to occur at different elevations on a single mountain
- B.no vegetation of any kind to occur above a certain fixed elevation always
- C.identical vegetation to occur at every elevation on a single mountain
- D.a factor entirely unrelated to how vegetation varies with elevation
Show the answer
A. distinct vegetation zones to occur at different elevations on a single mountain
Altitude-driven climate differences create distinct vegetation zones at different elevations on mountains.
- Practice question 2
Deciduous trees, common in savanna and monsoon vegetation zones, shed their leaves during a defined dry season to
- A.a purpose entirely unrelated to water availability
- B.maximize water loss through their leaves during that period
- C.conserve water
- D.have no measurable effect on their own water balance
Show the answer
C. conserve water
Shedding leaves during the dry season is specifically a water conservation strategy for deciduous trees.
- Practice question 3
Mangrove vegetation, adapted to saline, waterlogged conditions, is commonly found along
- A.tropical and subtropical coastlines and estuaries
- B.a setting entirely unrelated to coastal or estuarine environments
- C.high-altitude mountain slopes, with no connection to coastlines
- D.cold, polar tundra regions, with no connection to coastlines
Show the answer
A. tropical and subtropical coastlines and estuaries
Mangroves are specifically adapted to, and commonly found along, tropical and subtropical coastlines and estuaries.
