ES 240 UVIC - MIDTERM 2 EXAM
QUESTIONS AND ANSWERS 100% PASS
Nutrient Cycles - ANS Chemical building blocks that cycle through Earth's systems and can be
expressed on a global scale.
Where does most of Earth's energy come from? - ANS The Sun. The energy input and output
is the same going on and off world.
Do nutrients cycle off-world? - ANS No, they cycle exclusively through the planet itself.
Macronutrients - ANS Elements required in large quantities. Carbon, Oxygen, and Nitrogen.
Micronutrients - ANS Elements required in lower concentrations. Chloride, Iron, Manganese,
Zinc, Sodium, etc.
Toxicity - ANS Too much of one thing can be bad, but a little bit is ok. Elements like Nickel and
Copper can be toxic.
How do organisms and environments develop tolerance? - ANS With long-term exposure to
toxic things.

, Halophytes - ANS Plants that can tolerate high levels of salinity.
Soil - ANS Requires both abiotic and biotic conditions to form. It stores nutrients and water to
provide to the organisms living in it.
Parent Material - ANS The official geology of a soil.
What affects how soil forms? - ANS Climate, Topography, Organisms, and Time.
Pool - ANS Description of where materials are found. Also known as compartments.
Flux - ANS Quantitative value representing the transfer of material between pools.
Source - ANS Exporter of materials.
Decomposers - ANS The major consumers of carbon.
What are the major pools of Carbon? - ANS Rocks, soil, vegetation, ocean sediments, and
animals.
What are photosynthetic organisms known as? - ANS Big "movers" of Carbon. they move it
between the atmosphere and ecosystems.
How does ocean upwelling affect Carbon? - ANS Upwelling brings Carbon and some other
nutrients back up to the surface of the ocean.
