Ecological Energetics
-
Energy
-
-
- can be transformed from 1 form to another
- cannot be created or destroyed
Pyramid of Biomass
-
biomass - measured:
FRESH mass
- :red_cross: more variable
- :check: still give accurate representation
DRY mass
- :check: more accurate
- :red_cross: more time consuming
- :red_cross: organisms killed
disadvantages
- difficult to construct - laborious + expensive
- impossible measure ALL individuals
- only show dry mass @ 1 particular time
- eg. small producers - high birth, growth + death rate
- eg. large producers - lower turnover rate
advantages
- more representative than pyramid of no.
Pyramid of Numbers
-
disadvantages
- simplistic
- inaccurate representation
- do not show SIZE
- difficult to show scale
- difficult to decide which trophic level organism in
advantages
- show simplified representation
INVERTED
- 1 very large producer
- e.g. oak tree
