●● 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
●● Define ecosystem productivity
Answer: diverse systems have higher net primary productivity
,●● Define ecosystem services
Answer: direct and indirect benefits that humans derive from organisms
and ecosystems
●● Define existence value
Answer: economic value of a system and our willingness to mitigate
biodiversity loss
●● What are provisioning services?
Answer: raw materials (food, fuel, fiber, medicine, genetic resources)
●● What are regulating services?
Answer: life support system (climate moderation, soil formation, erosion
control, water capture, flood control etc.)
●● Define ecosystem services
Answer: all direct and indirect benefits that humans derive from
organisms and ecosystems
●● What are cultural services?
Answer: cultural/intrinsic (aesthetics, recreation, education, spiritual
value, and physical/mental health)
, ●● What are supporting services?
Answer: primary productivity, nutrient cycling, pollination, and
biological control
●● What are the primary threats to biodiversity?
Answer: -habitat loss
-climate change
-invasive species
-overexploration
-pollution
●● What are characteristics of viruses?
Answer: -very,very small
-not a cell
-can not reproduce independently
-does not contain ribosomes or generate ATP
●● What are characteristics of bacteria?
Answer: -small but bigger than virus
-single cell
-reproduce independently
