CH 4,6,8 partial review

Carbon cycle Nitrogen cycle Hydrologic cycle Phosphorus cycle 11. It involves bacteria, which trap this chemical element in a way which allows multicellular plans and animals to metabolize it. Carbon cycle Nitrogen cycle Hydrologic cycle Phosphorus cycle Biogeological cycle

Carbon cycle Nitrogen cycle Hydrologic cycle Phosphorus cycle 13. This cycle’s inability to be soluble in water limits the growth of producer populations in many freshwater streams and lakes. Carbon cycle Nitrogen cycle Hydrologic cycle Phosphorus cycle Biogeological cycle

14. It does not involve death, decay, or decomposition to function. Carbon cycle Nitrogen cycle Hydrologic cycle Phosphorus cycle Biogeological cycle

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.

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

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.

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

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.

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

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)

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

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
