JMU BIO 150: EXAM 1 QUESTIONS WITH 100% VERIFIED ANSWERS!!
Define biodiversity - (answer)the diversity of plant and animal life in a particular habitat (or in the world
as a whole)
Define genetic diversity - (answer)the total genetic information contained within all individuals of a
species, population, or community
Why is genetic diversity important? - (answer)provides the raw materials for adaptive change
Define adaptive change - (answer)change in response to the environment's "natural selection:
Define species diversity - (answer)the diversity of species present in a community
Why is species diversity important? - (answer)species have a particular "role" in a system, so the
addition or loss of a species may have consequences for the entire system
How is species diversity measures? - (answer)-species richness
-species abundance
Define species richness - (answer)number of species in a community
Define species abundance - (answer)The number of individuals of each species
Define ecosystem diversity - (answer)measure of the variety of biotic components in a region along with
abiotic components
Why is ecosystem diversity important? - (answer)ecosystem functioning is dependent on interacting
member organisms with their environment
Define system stability - (answer)diverse systems are resilient after and resistant to disturbances
