25
trophic structure
relationships between organisms in a community
26
pros of living in groups
locating food assistance with offspring access to mates protection in numbers
27
uniform
seagulls
28
ultimate cause
effects reproduction
29
associative
behavior changed with reward or punishment (pavlov's dog
30
iteroparity
repeated reproduction
31
fixed action pattern
once initiate will continue until completed (yawn)
32
eutrophication
surplus of nutrients causes lack of oxygen
33
trophic level
each level in a food chain 10% of energy is passed to the next level
34
R selection
density independent
35
dominant species
most abundant
36
cons of living in groups
competition for food spread of disease
37
clumped
oasis trees
38
trade winds blow
east to west
39
innate
always known
40
