Mercury expands and contracts in response to changes in temperature
Mercury thermometer
Mercury expands and contracts in response to changes in temperature
Mercury thermometer
Determine the relative humidity in the atmosphere
Sling psychrometer
Measure atmospheric pressure
Barometer
Measure light levels or intensity
Light meter
Measure the water content and the refractive index of liquids
Refractometer
measure the hydrogen ion activity in solutions
pH meter
pH level less than 7
Acidic
pH level is 7
Neutral
pH level is greater than 7
Basic
Measure wind speed, direction, and pressure
Anemometer
Used for collection, storage and transport of specimens
Sample bottles
Used to collect water samples for dissolved oxygen analysis
DO (Dissolved Oxygen) Bottles
Used to measure depth of holes
Depth gauge
Used for attracting and trapping small, fast-moving animals
Bait trap
Measures the cover (or shade) of vegetation
Densiometer
Measures water transparency or turbidity (cloudiness)
Secchi disk
Measures the angle of slope/tilt of an object with respect to gravity
Inclinometer
Measures relative humidity by comparing temperature differences between a wet bulb and a dry bulb
Hygrometer
How close a measurement is to the true value
Accuracy
Measures how close the results are to one another
Precision
(TYPE OF PRODUCER) Produces the food
Autotrophs
(TYPE OF PRODUCER) Convert light into energy through photosynthesis (e.g. plants)
Photoautotrophs
(TYPE OF PRODUCER) Obtain energy from inorganic chemical reaction through chemosynthesis (e.g. bacteria, archaea)
Chemoautotrophs
(TYPE OF CONSUMER) Feed on producers and other consumers (carnivores, herbivores, and omnivores)
Heterotrophs
(TYPE OF DECOMPOSER) Feed on decaying matter
Saprotrophs
Utilized in photosynthesis
Light energy
Compromises most of the earth’s surface; essential for living
Water
Where gas exchange occurs; Compromises the earth’s atmosphere
Air
With H2O as its most abundant compound
Soil
Types of soil
Sandy soil, slit soil, clay soil, and loamy soil
Measure the hotness or coldness
Temperature
Affect population growth of organisms; change in quantity in/directly influence the balance in nature
Limiting Factors
Examples of limiting factors
Competitors, disease and parasites, weather, fires, available habitat, and predators
Event that brings about mortality to organisms; Plays a significant role in shaping the structure of individual populations and the character of whole ecosystems
Ecological Disturbances
What kind of disturbances are these: localized wind events, drought, flood, small wildland fires, disease outbreaks?
Minor Disturbances
What kind of disturbances are these: tropical cyclones, volcanic eruptions, tsunami, epidemic?
Major disturbances
Occurs in areas where there was no previous soil or vegetation (from scratch)
Primary succession
Occurs in an area that is previously had vegetation but a disturbance or damage occurred
Secondary succession
