IB ESS Fall Final Exam Review 2017
Closed System - correct answer ✔✔Energy but NOT matter is exchanged across the boundaries
Ex. Atoms and molecules
Open System - correct answer ✔✔BOTH matter and energy are exchanged
Ex. People and other living things
Isolated System - correct answer ✔✔Neither energy nor matter is exchanged
Ex. Universe (not truly any real examples)
System - correct answer ✔✔An assemblage of parts and the relationships between them, which
together constitute an entity or whole
Transfer - correct answer ✔✔If the movement does NOT involve a change of form or state
Transformation - correct answer ✔✔If it does involve a change of form or state
Positive Feedback - correct answer ✔✔Occurs when a change in the state of a system leads to additional
and increase change (does not go back to normal, bad things)
Ex. Global warming
Negative Feedback - correct answer ✔✔Reducing the effect of the system's components but goes back
to normal
Ex. Good things that happen to the Earth
Flow - correct answer ✔✔Input into the system
Output out of the system
, (arrow going into box) BOX (arrow leaving box)
input output
Leaching - correct answer ✔✔A transfer process that takes water from soil and deposits it into lakes or
other bodies of water
1st Law of Thermodynamics - correct answer ✔✔Energy cannot be destroyed nor created but it can be
transferred
2nd Law of Thermodynamics - correct answer ✔✔Entropy always increases, there is always a loss into
the air and not everything can be transferred
Entropy - correct answer ✔✔Un useful energy because it is energy that is lost between transfers
Ecological Niche - correct answer ✔✔The role and position a species has in its environment
Biome - correct answer ✔✔A collection of ecosystems sharing similar climatic conditions
Tundra - correct answer ✔✔-Located in Alaska, Northern Canada, edges of Greenland, Northern
Scandinavia, Northern Siberia and Russia
-Earth's coldest and harshest biomes
Deserts - correct answer ✔✔-Located away from water
-Extremely hot and low biodiversity because not many organisms are able to sustain the heat and lack of
water
Rain Forests - correct answer ✔✔-Located in the tropics and near water or along rivers
-Wet, hot and humid
Diversity Index - correct answer ✔✔Measure of diversity which takes into account the number of species
present as well as the relative abundance of each species
