1What is biomass?
Mass of carbon in an organism
2How is biomass measured?
Dry mass per unit area
3What is used to measure energy?
A calorimeter
4What does burning biomass calculate?
Chemical energy content
5What does temperature change indicate?
Energy released by burning biomass
6What is GPP?
Total chemical energy in plants
7What is NPP?
Energy available for growtheproduction
8How is NPP calculated?
NPP = GPP - R
9What does R represent?
Respiratory losses
10What is net production for consumers?
N = I - (F + R)
11What does "I" stand for in NPP?
Chemical energy ingested
12What does "F" stand for in NPP?
Energy lost in fecesrine
13What does "R" stand for in NPP?
Energy lost via respiration
14What is energy transfer efficiency?
(Energy transfer ÷ Input energy) x 100
15What is an example of NPP?
Grass = 20,000kJ; NPP = 12,000kJ
16What are trophic levels?
Steps in a food chain
17What is dry mass?
Biomass without water content
18How is GPP energy used?
For respiration and NPP
19What is secondary production?
Consumers’ biomass increase
20What is primary production?
Plants' biomass production
