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
What type of plant adaptations will one find in tropical rainforest?
buttresses for support; wide leaves to catch water and sunlight; epiphytes (plants growing in tops of trees) for more sunlight
erosion of rocks; the geologic cycle
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
What is soil texture ?
The particle size distribution in soil [relative proportion of sand, silt and clay-sized particles]
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 abiotic factor determining where an aquatic organism lives
what is salinity
Three general types 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)
What properties of soil affect its ability to hold water?
porosity, permeability, particle size
the relationship between altitude, latitude, and average temperature
Higher altitude OR higher latitude == colder temperature
Related species receiving different traits due to selective pressures
divergent evolution

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
What is the process involved in the recycling of carbon dioxide?
photosynthesis and respiration
A collection of interbreeding organisms of a specific species living together in a region or area.
