Lesson 2 - Energy and Ecological Pyramids Flashcards
(6 cards)
1
Q
How do producers receive energy
A
they capture the radiant energy from the sun and store it in biological (organic) molecules like carbohydrates (sugar)
2
Q
How do consumers receive energy
A
receive energy by “eating” another organism and taking any energy
that is stored in the tissues
3
Q
Is 100% of the energy transferred? Why?
A
No, because as we learned before no transfer of energy is 100% efficient so each trophic level loses energy
4
Q
What are the 3 types of ecological pyramids?
A
- Pyramid of Numbers
- Pyramid of Biomass
- Pyramid of Energy
4
Q
What is the 10% rule
A
no transfer of energy is 100% efficient so each trophic level loses energy
5
Q
Pyramid of numbers
A
Initially used to show decreasing energy transfer but was later discounted as true energy flow could not be shown
