Evolution
Adaptation is different from evolution in that
adaptation is an inherited trait to raise its survival chances whereas evolution is the change in genetic characteristics
2 benefits of wetlands
filtering water (purification)
holding water (natural dams; flood controlP
Carbon dioxide in the atmosphere is only absorbed by
Plants
unrelated species evolving to have similar traits
Convergent evolution
Terms for free-swimming organisms vs. bottom dwellers
What are nekton vs benthic organisms
Which biome is susceptibility to fires, low to moderate rainfall, few to no trees
Grasslands
The particle size distribution in soil. More sand means water moves more quickly through the soil (has higher permeability)
Species native to a particular area
Endemic species
three adverse consequences of the bottleneck effect
Inbreeding, less able to adapt, inherit genetic diseases
Most important biotic factor determining where an aquatic organism lives
what is salinity
Three general categories of adaptions are changes in ...
Size, shape, and color
_______ are organisms that get their food by breaking down dead organsims.
Decomposers
What happens at the zone of intolerance
The population dies out (or does not exist)
Why is water important in the water cycle?
It regulates water patterns, support ecosystems
the relationship between altitude, latitude, and average temperature
Higher altitude OR higher altitude == colder temperature
Related species receiving different traits due to selective pressures
divergent evolution
What are the 2 general rules of Island Biogeography
The HIGHEST species richness will be found on LARGE islands NEAR the mainland
what is the change of water from liquid to a gas?
evaporation
Two things that define a biome
Climate (precipitation; temperature) and Organisms
A collection of interbreeding organisms of a specific species living together in a region or area.
