What term describes the maximum population size that can be supported by available resources in an ecosystem?
Carrying Capacity...once a species reaches carrying capacity, population growth is close to zero.
What do decomposers do in an ecosystem?
They break down dead matter, allowing nutrients to be recycled.

Shield, cinder cone, or stratovolcano
Shield
Name ONE of the two causes of global ocean currents.
Which one of these has THE LEAST impact on carrying capacity?
a. available food
b. color of the organism
c. spread of disease
Color of the organism...although color can help avoid predators/attract mates, the affects of food and disease are usually stronger.
Which trophic level on an energy pyramid has THE MOST available energy?
Producers, who convert solar energy to chemical energy
What is the name for organisms that can make their own food?
Autotrophs --> plants, algae, etc.
Auto- "self"
-troph - "feeder"
What is the name of the evil sorcerer in "The Lord of the Rings" series?

What causes the movement of tectonic plates?
Convection currents in the mantle move the plates, on average, 2-5 centimeters per year.
What is the thermocline?
A layer in the ocean where the temperature changes very quickly as you get deeper....gets really cold really fast.
Which type of growth curve is J-shaped......
exponential or logistic?
Exponential growth shows unrestricted population growth, this can occur when an organism enters a new environment with lots of food and no predators.
Only 10% of energy is transferred between trophic levels through feeding.....where does the other 90% go?
The energy is lost as heat - the consuming organism uses this energy to perform bodily functions and move.
Place the following organisms in the correct food chain sequence?
hawk mouse snake grass
grass-mouse-snake-hawk

81 against the Toronto Raptors. Look up his highlights on YouTube......
Name 2 common volcanic gases?

Disease, food, predation, parasites, stress from overcrowding.....
Which one is more complex - the food web or the food chain?
The food web shows many more interconnected feeding relationships.
What is another name for primary, or 1st, consumers?

What type of relationship exists between two animals where one of them benefits while other is unaffected/doesn't care?
Commensalism - remember the shark and the remora fish
Describe the role of a keystone species....remember the starfish? And the otters?
The affects of a keystone species are very large in an ecosystem -- their removal can cause entire systems to collapse.
The starfish kept mussel populations in check, increasing species diversity.
The otters controlled populations of sea urchins, allowing kelp forest to grow.
