The greater a habitat’s biodiversity, the greater will be that
habitat’s -
A
sustainability over time with varying conditions.
B
consumption of energy in the form of sunlight.
C
temperature ranges across the seasons.
D
distance to the nearest water source.
Over time, a shallow pond fills with plants, such as duckweed
and cattails. These plants -
A
will die off quickly in the shallow water.
B
support ecological succession from pond to marshland.
C
will grow into larger trees as they mature.
D
eventually will dry out and create a fire hazard.

Why does biodiversity contribute to a habitat’s sustainability?
4
A
The more plants and animals in a habitat, the greater the
biomass, which is how habitats store energy.
B
The greater the number of species, the more competition
there is for food between predators, which sustains their
populations.
C
Changing conditions that harm one species leave other
species to survive and perhaps even thrive.
D
Landforms change shape less frequently when there is a
greater number of species using the land.
A habitat that receives little or no precipitation will most
likely be suitable for organisms that -
A
hibernate for long periods of time.
B
are covered in thick fur to keep warm.
C
spend most of the day in the sunlight.
D
store large quantities of water internally.
