Chapter 5
-
Species evenness- the measure of whether a particular ecosystem is numerically dominated by one species or are all represented by similar numbers of individuals
-
-
An example of a bottleneck effect can be: species almost extinct, but recover with little genetic variation
-
-
Species: a group that is distinct from other groups in terms of size, behavior, or biochemical properties and can interbreed to produce viable offspring

Water, solar energy, and carbon dioxide are needed for photosynthesis.
Runoff is when water moves across land surface into streams and rivers eventually reaching the ocean.
The Carbon Cycle has 6 processes 1-photosynthesis
2-respiration 3-exchange 4-sedimentation 5- extraction 6-combustion
