Strategy of Ecosystem Development Flashcards
1
Q
Gross production (P/R)
A
Increases quickly –> peak –> stabilize as R increases and production tends towards quality over quantity
2
Q
Net community production
A
lower yield over time (similar to gross production)
3
Q
Community respiration
A
low when B low –> increase w/ increasing B
4
Q
P/R ration
A
approaches 1 as community matures
5
Q
P/B ratio
A
as more biomass –> ratio decreases (reflects energy allocation in sys)
6
Q
B/P & B/R
A
amount of biomass/energy unit increases as time & biomass increase
* @ some point, sys using incoming energy @ max rate w/ X additional biomass (would correspond w/ climax community theory)
7
Q
Food chains
A
simple –> complex
