ARCTIC TUNDRA by connor richardson #ecosys3

Biotic: The arctic tundra includes Antarctic hair grass, Antarctic Pearlwort there plants. salmon and Arctic char, Lichen, mosses, sedges, widow shrub, snow geese, red-necked Loons, ptarmigan, Dall sheep, Caribou, musk oxen, wolves, brown bears, wolverines.

Carrying capacity

Abiotic: Permafrost, air, gases, wind, water, ice, light, snow, sunlight receives less sunlight due to less radiation. windy and dry because of the lack precipitation  

Carrying capacity-A biological species in a environment is the maximum population size of the species that the environment can sustain.

the population needs food, water, shelter. The polar bear died off for awhile because they weren't able to get food and shelter.     

limiting factors in the arctic tundra
food, water, shelter mostly food.

Aquatic Arctic moss, Xathoria, dwarf shrubs, Graminiods. there energy transfers to the arctic hare, lemming, muskox, and caribou. And there energy go to arctic fox, ptarmigan. There energy goes to wolverines, brown bear,

 the reason why producers have the biggest part of the pyramid is because there are so much producers we cant keep track of them. There are so much producers in the world if we were to get rid of all the plants in the world we probably would die. The reason why top consumers are at the top is because there are so little of them they will never out go producers




2. 6CO2 + 6H2O ------> C6H12O6 + O2
Sunlight energy

Where: CO2 = carbon dioxide
H2O = water
Light energy is required
C6H12O6 = glucose

O2 = oxygen


sunlight, the chlorophyll that is present in green plants, water and carbon dioxide in the air. Photosynthesis is necessary not just for plants to make food for themselves, but for animals, including us eventually.


Photosynthesis takes place inside plant cells in small things called chloroplasts. Chloroplasts contain a green substance called chlorophyll. This absorbs the light energy needed to make photosynthesis happen.Plants can only photosynthesise in the light.


Electromagnetic (light) energy into chemical (sugars) energy.



1. Tropism- The turning of all or part of an organism in a particular direction in response to an external stimulus.  

3. Heliotropism, a form of tropism, is the diurnal motion or seasonal motion helped the plants because whenever the seasons' changed the plant wilted.

The Role of Decomposers

Decomposers are important because they give nutrients back to producers so they can photosynthesisize and create food. If there weren't decomposers plants would die, then we would die.
