Lesson 10: Primary Productivity/Trophic Levels/10% rule Flashcards
Unit 1
1
Q
Primary Productivity
A
The rate at which plants in an area convert sunlight into glucose or plant tissue (photosynthesis)
Primary Productivity
= Energy/ Area/Time
2
Q
Respiration Loss (RL)
A
The energy plants use up for their cellular respiration
Primary Productivity Equation
NPP = GPP - RL
3
Q
Trophic Pyramid
A
Shows how much energy flows through different levels in a food chain
4
Q
What is the Second Law of Thermodynamics?
A
Some energy is lost as heat each time energy is transferred
5
Q
10% Rule
A
Only 10% of energy from one trophic level is passed on to the next trophic level
