Energy In Ecosystems Flashcards
1
Q
Producer - tropic level
A
Make their own food
2
Q
Primary consumer
A
Herbivores that eat producers
3
Q
Secondary consumer
A
Organisms that consume primary consumers
4
Q
Tertiary consumers
A
Organisms consume secondary consumers
5
Q
Saprobiants
A
Organisms decompose dead matter releasing nutrients
6
Q
What is a food chain
A
Sequence of organisms that are connected by feeding and energy transfer
7
Q
What is biomass
A
Total mass of living material present
In a specific time
8
Q
Calorimetry
A
- Dry biomass until mass remains constant obtaining dry the mass.
- Weigh the dry mass and burn in calorimeter. 3. Change intemp provides estimate of chemical energy present
9
Q
Gross primary productivity
A
GPP is the amount of light energy that plants convert into organic matter e.g. Glucose.
10
Q
Net primary productivity and equation
A
Chemical energy that is available to the next tropic level after respiratory losses.it is energy converted into biomass
