Ecosystem Portfolio
Taiga Biome

Biotic Factor

1.animals like,snow owl,reindeer,polar bears,white foxes,etc.

2.plants like,heaths and mosses

Abiotic Factors

1.Stron winds

2.little rainfall

3.short summer days

4.long and cold winters

5.poor soil

6.premafrost-a layer of permanently frozen subsoil

Carrying Capacity

the number of organism that a region can support without enviromental degragation.

limiting factors and predator/prey

One example of predator and prey in the Taiga is the relationship between the Snowshoe Hare and the Lynx. The snowshoe hare is a major prey item for a number of predators.During the winter the coat is white to blend into the snow, and the coat is tan in the summer to hid in the woods. The Lynx is a good climber and swimmer. The Lynx diet mostly is of the Snowshoe Hare and their numbers.It will also hunt medium-sized mammals and birds if hares are not found.

Energy Roles

producers:organism that produce their own food

examples: twinleaf,mosses,birch,willow,and aspen

herbivores:any organisms that consumes plant matter as the main component.

examples: moose,red squirrels,snow hares,and beaver

carnivores:an organism that consumes animal tissue or ohter animals

examples:bobcats,tigers,badgers,and polar bears

examples: brown bears,arctic wolves,and humans

omnivores: an organism that consumes both plants and animals

decomposers: an organism that process any decaying or already dead organism

examples:bacteria and fungi

scavengers:an animal that feeds on carrion, dead plant, or refuse

examples: wolves, hawks, eagles, and bears

producer explanation:

trees are mostly evergreens, with a couple of deciduous (trees that lose their leaves in fall) trees mixed in. Evergreens are mostly firs, pines, spruces, etc. A type of evergreen that actually loses its leaves is a tamarack. Another is a larch.
examples: club moss, lichen, shin leaf, and twin leaf

Food Chains and Food webs

the difference between a food web and a food chain is that the food web shows how other organisms kill each other off/eat each other, and the food chain shows how the energy is transferred from organism to another organism.

removing a population

removing a population could change the amount of an organism, it could decrease the population, by an animla deining off,or going extinct.

tropich Levels and Energy pyramids

Shape of the pyramid

The reason of the shape of the pyramid it`s showing how the energy is being transferred from organism to organism.

PRODUCERS: the producers are at the bottom, because the producers start the food chain/web, they give the energy from the sun and transfer their energy to the next organism that would eat it.


cardon dioxide + water + light/glucose + oxygen = photosynthesis

CO2 + H2O + C6H12O6 + O2 = photosynthesis


the turning of all or part of an organism in a particular direction in response to an external stimulus

examples: sagirrania, nelumbo ,spirodela, and vallisheria

these help other plants live, because they have really long roots so they`re able to get to the water.

Role of Decomposere

Decomposers are vital to the ecosystem, because it would help other living organisms live by eating dead or dying plants.

if there wasn't any decomposers, then the living animals wouldn't be able to survive by not eating them.

examples: fungi, sow bugs, and honey fungus
