Transfer Of Energy Through Trophic Levela Flashcards
1
Q
What is a trophic level?
A
Feeding levels in food chains
2
Q
State what is found at each trophic level.
A
TL1 - Producer
TL2 - Primary Consumer
TL3 - Secondary Consumer
TL4 - Tertiary Consumer
3
Q
Why is the transfer of energy from light energy to TL1 inefficient?
A
- wrong wavelength so not absorbed by chlorophyll
- misses the chloroplasts
- reflected from leaf surface
4
Q
Why is the energy transfer between trophic levels inefficient?
A
- some parts of organisms are inedible
- some parts of organisms are indigestible
- organisms respire which releases heat energy
- mammals release heat through respiration to maintain body temperature
5
Q
How is the % efficiency of energy transfer calculated?
A
( Net production of trophic level / net production of previous trophic level ) X 100
