Key Term Abiotic Factors Physical or NONLIVING component of an ecosystem

Rocks, Sand, Cliffs

Snow, Rain, HailWind

Sun, Heat, Cold

Permafrost (permanent layer of frost) Little rain or snowfall Least diverse biome Flat terrain Constant low temperature

Tundra

Coniferous Forest(TAIGA)

Spruce and Fir Trees (Cone Plants) Mosses, lichens, small shrubs Winter snowfall Short, warm summer days Snow completely thaws

Deciduous Forest Distinct 4 seasons Trees lose leaves in the Fall Richest Soil Oaks, Maple, Hickory, Chestnut Abundant snow and rainfall Squirrels, Deer, Birds, Fox, Skunk

Desert Extreme temperatures Little precipitation Poor, dry conditions Thorny plants, cacti Rodents, insects, reptiles, camels

Grassland Tall, Mixed or Short grass Deep, porous soil Low-medium precipitation Wolves, grasshoppers, jackrabbits,

badgers, rattlesnakes, birds, Low winter temperatures

Rainforest Most Diverse Minimal season variation Rainfall, Humidity, Precipitation High Vegetation is dense Broad leafed plants Insects, fungi, monkeys, birds, frogs

Purpose of Lab Graph data of temperature and

precipitation Compare biomes Analyze San Diego biome data Analyze a set of unknown data

Steps to do the Lab

Graph the San Diego data on graphing paper

Use Microsoft Excell to do steps a~d (on page 601)

Graph your assigned “Unknown” from page 601 (a-l)

Study your graph and label the appropriate biome it belongs too

How to use Excell

Turn on the power of the computer Move the mouse to “Start” and click

one time, holding the button down Drag the mouse to “Programs”, then

over to “Microsoft Excel” and release You are in “Microsoft Excel”

Making a Data Table

1. Type the initials of the months in the first column2. Type in the monthly precipitation in the second column3. Type in the monthly temperature in the third column

Example of Data Table

Graphing Your Data (1)1. Select all of the data and hit the chart wizard icon2. Click on the “Custom Types” tag3. Select the “Line-column on Two Axes”4. Click next twice5. Select no legend and type in the necessary info.6.Click finish

Graphing Your Data (2)1. Double click on the left Y axis bar and under “Scale” put in the following values:

Minimum: 0 Major unit: 2Maximum: 36 Minor unit: 1

2. Double click on the right Y axis bar and under “Scale” put in the following values:

Minimum: -36 Major unit: 4Maximum: 36 Minor unit: 1
