Answer: C
Topic: 43.1 Human activities threaten Earth’s biodiversity
Bloom’s Taxonomy: 1-2: Remembering/Understanding
Learning Outcome: 43.1, V&C 5
Global L.O.: G7
2) Estimates of current rates of extinction
A) indicate that rates of speciation equal extinction, so an equilibrium has been reached.
B) suggest that one-half of all animal and plant species may be gone by the year 2100.
C) indicate that rates may be greater than background extinction rates seen in the fossil
records.

3) It is estimated that 99% of all species that ever lived are now extinct. Why, then, do we say we
are now experiencing an extinction (loss of biodiversity) crisis?
A) Humans are ethically responsible for protecting endangered species, but protection is
limited.
B) Most of the species on Earth have been identified, so rates of extinction can be
quantified.
