5. 11. A caterpillar eats a leaf
11. A caterpillar eats a leaf. Of this food, the majority is digested and:
Is added to the caterpillar’s bodily material.
Is excreted as waste material.
Is consumed by microorganisms inside the caterpillar’s digestive system.
Converted to energy, allowing the caterpillar to move around and continue living.

6. 12. Ultimately, all energy used on Earth came from:
Producers
Consumers
Earth
A Star

7. Of the 3rd law of thermodynamics
24. Most of the time, 90% of energy created by producers or consumed by consumers/detrivores is NOT transferrable to the next trophic level because
Of the 3rd law of thermodynamics
The energy was converted into heat and shed into the environment over the organism’s lifetime
The energy was converted to matter to help the organism build itself, and most consumed is not used productively
The 90% energy lost was never converted from the matter consumed, and instead excreted.

8. 13. Typically, the % of energy transferred from one trophic level to the next is:0%
10%
25%
50%

9. 15. Energy flows through an ecosystem:
In1 direction only.
By getting recycled.
Separately from matter.
With at least 10% efficiency from one trophic level to another.

10. 16. What is the driving force behind groundwater movement?
Additional water leaching down
Solar energy
Gravity
Terrestrial osmosis

11. 17. Wind transporting matter from one location to another is due to:
Solar energy
Gravity
Differences in atmospheric pressure
None of the above (provide your own example)

12. 19. A change in the __________ cycle could induce a(n) __________ in an ecosystem.
Oxygen, geological change
Water, acid rain
Sulfur, eutrophication
Nitrogen, hurricane
Carbon, climate shift

13. 1. A simple ecosystem requires which to function?
I only
II only
III only
I and II
I and II and III
Producers
Decomposers
Consumers

14. There will be many more questions unrelated to these
There will be many more questions unrelated to these. Create flash-cards to review your notes. Review your concept map of weather/climate and biomes. Quiz each other. Do your best.
