Which type of ecological succession occurs after a flood?
Secondary succession
Observation or Inference
"The monkey fell out of the tree because it was sleepy."
Inference
A monkey can fall out of a tree for a number of reasons.
Buffers
What do buffers do?
Prevent a change in pH
What is homeostasis?
Maintaining stable internal conditions
If there is 100,000 kcal of energy available from the producers, how many kcal do secondary consumers get?
1000 kcal
(10% of energy is passed to the next level)
Producers = 100,000
Primary consumers = 10,000
Secondary consumers = 1,000
Tertiary consumers = 100
Variables
What is the difference between independent and dependent variables?
Independent variables are being tested
Dependent variables are being measured
pH
What are the ranges for acids, neutrals and bases?
Acids: 0-6
Neutral: 7
Bases: 8-14
Identify the following example as a positive or negative feedback loop:
Body temperature increases. The body starts to sweat. Body temperature returns to normal. Sweating stops.
Negative feedback loop
The loop is returning the system back to a set point.
Bees pollinating flowers and receiving nectar in return is an example of which ecological relationship?
Mutualism
Graphing
On which axes do independent and dependent variables go?
HINT: DRY MIX
Independent variables go on the x-axis
Dependent variables go on the y-axis
Properties of water
Which 3 properties of water help a plant get water from the ground into its tissues?
Adhesion, cohesion, capillary action
Identify the following example as a positive or negative feedback loop:
A finger is cut and bleeding begins. Platelets signal for more platelets. More platelets arrive and signal for more platelets. This continues until the bleeding stops. The call for platelets stops.
Positive feedback loop
The loop is amplifying the process until completion
Which biome is represented by the climatogram above?
Grassland
Medium temperature, medium precipitation
