Body Size Flashcards
1
Q
5 ways that body size affects organism form and function
A
- Complexity
- Rates
- Abundance
- Surface Area
- Strength
2
Q
complexity
A
- # cell types, tissues, organs
- larger body size corresponds with more cell types
- division of labor increases efficiency
3
Q
rates
A
metabolism, development, locomotion
4
Q
metabolixm
A
larger animals need more absolute energy to maintain functions, but less energy/g of body mass
5
Q
generation time
A
larger organisms have longer development times than small ones
6
Q
locomotion
A
larg animals move more rapidly than small ones
7
Q
abundance
A
- population density
- larger size means lower abundances
8
Q
surface area
A
larger organisms have a larger absolute and smaller relative surface area/volume
9
Q
strength
A
- strength to mass ratio decreases as size increases
- proportional to their size, small animals are stronger
10
Q
adaptations that increase surface area
A
- flattening–gills
- folding–digestive tract
- branching–capillaries
