Transcript of Taiga

Day 1
Day 2
Day 3
General characteristics
food chain
Climate ;
Taiga's climate is extremely cold. During the winter the lowest temperature may go to as low as -65 F and highest may be around 30 F. Brr!
During the summer the temperature is a huge difference. The lowest may go to around 30 F and highest may be to around 70 F! That's a lot better then the winter if you don't want to freeze to death.

global positioning ;
Taiga is found in the Northern parts of North America, Europe and Asia
The geography of coniferous forests includes landforms, elevation, soil, mineral resources, and water resources
Carnivore, wolverines,Bobcat,lynx
Detritovore, quagmires , G-quakes
Vascular plant,black spruce,maple moose
Non vascular plant,maple moss
Gymnosperm, pines
Angiosperm,black barries
Mutualistic relationship,balsam fir moss
Commensalistic relationship, birds nest

Work of Day 2

cuticle protects the outer surface of the flower. although

stomata is a tiny openong at the bottom of flower .used for gas exchange

roots and root hairs used for the present a large surface area for absorption. (larger the surface area, greater is the absorption).

xylem is the thick wall made up of lignin which supports the plant

period 1st

Ecologists study population geographic range , density , and distribution , growth rate and age structure
factors that can effect population size are by birthrate,deathrate,rate of immigration and rate of emigration
Carrying capacity the maximum number of individuals of a particuler species that a particuler enviroment can support carry capacity is determind by limiting factors .
r-strategists are species that can grow and reproduce fast to increase their population. They are also known as small body animals .k-strategists are species that grow and reproduce more slower than the r-strategists do..also they are known for having large body animals
example of r & k strategists are r for rabbites and k for black bears in the tiaga biome.
phloem vasculor tissue responsible for the transport of nutrients and the carbohydrate produced by photosyntheseis

flowers is the seed bearing structure of an angiosperm

cones is the seed bearing structureof the gymnosperm
cuticle: is a protecting film covering the epidermis of leaves, young shoots and other aerial plant organs without periderm.
xylem: carries h20 upward through out the roots: and whole plant
phlome: transport nutrients and the carbohydrates produced by photosynthesis
vien: vasculor tissue
Guard cell: guards the stroma
stroma: opening of the leaf for gas exchange Epidermis: One or more layers of cells forming the outermost portion of the skin or integument
Mesophyll: carries out photosynthesis
chloroplast: a plastid containing chlorophyll and other pigments, occurring in plants and algae that carry out photosynthesis

Black bear
density dependent factor are competition,predation,herbivory,parasitism disesase, stress from overcrowding
density inpdependent factors are usual weather,hurriance,droughts,floods,natural disasters,fires
If the exponential growth occurred in a population then there be a mix up of different animal populations decreasing or increasing .changing food webs into different orders.
mutations modify climate stuctures and enviromental functions due too changes on animals for example bird learning to fly
gene flow is the transfer of alleles or genes from one population to another.For example a black bear migrating over to a grizzly bear population
nonrandom Homozygotes increase in frequency, heterozygotes decrease in frequency.
genetic drift an event that eliminated a large population. An example would be black bear taking over the place of wolverens
natural selection the destruction of nature.an example would be men cutting down trees destroy food for the animals in that biome.
flower from biome
Meristems are tissues within a plant that are
undifferentiated-that is, they have no defined identity
like being "leaf tissue" or "stem tissue".

seeds Seeds contain the sporophyte embryo, food for the embryo, and a protective coat.
The embryo within the seed is dormant; it can survive for long periods without additional food or
water. When conditions become favorable, the embryo resumes growth as the seed germinates.
vasculer plant evergreen trees
non vasculer moss
Gynmnosperm pine cone trees
Angiosperm Labrador Tea
Monocot pine cone tree
dicot not many due to low tempatures in the area .
fruit Bog Blueberry
