Tundra #ecosys4

Biotic and abiotic factor that would acur in the tundra

Biotic- Polar bears , emperor panguins , artic wolfs , small cats , and a lynx

Abiotic- snow , ice ,rocks , fresh walters


                  The Tundra  (Carrying Capacity and Changes in Population  )

carrying capacity - the maximum amount of organism that an environment can hold

The resources needed for any population to survive are food, shelter and water

animals in the tundra can change in the ecosystem like the weather as it changes seasons and as plants and resources dies out there prey will have to go to the next thing for example of the White Fox goes extinct then the rabbits population will grow.


Limiting Factor - An environmental factor that tends to limit population size                            for example a fox has enough room and great home for a 4 more foxes but it has a limited amount of food  

A Polar Bear and a seal are two organisms that have a prey/predator relationship and if there is not a lot of fish than the seal will either move away or die out then the the polar bear will go extinct  

Producer - an organism that creates its own food ex. lichens       Decomposer - bacteria or fungus that breaks down the cells of dead organisms into a simpler substances ex.soil fungus                  Consumers - an organism that feeds of of plants or other animals ex.killer whale                                                     Herbivores - an organism that gets its energy from plants and only plants                                                             Carnivores - an animal that eats meat                              Omnivores - eating both animals and plants                        Scavengers - feed of waste or dead animals  


From dead species or corps


From other animals like seals and other animal and also if there any left berries


Many wolfs eat only meat like birds, arctic hares , ect.

Producers - receive energy from the sun (radiant energy ) then transform into food for plants so when the 1st level consumers eat producer , they are vital because they give the energy that the other consumers need for there every day life

A food web is more realistic in my ecosystem because , food webs go into more detail about the ecosystem and all there preys and predators but q for chain only follows 1 species and what there prey is

If you remove the wolverine th the polar bear and eagle would eat more of  the primary then the population of those two groups would decrease meaning eather they would have to move were there's a complete set of primarys and that one tertiary to balance the pyramid or die from hunger

the energy is given 10% to each level so as the producer gets the energy from the sun it uses 90% of the energy nutrients the pyramid has its shape because it shows the energy transforms and how the bottom has a bigger bottom which shows the energy and how much is stored the producer has more energy and as it rises the energy gets smaller

CO2 + H2O -----------> C6H12O6 = O2

carbon dioxide water       sugar            oxygen

photosynthesis needs water , radiant energy (sun) , and carbon dioxide and it produces  oxygen , and glucose

Water from the roots enters the leaf,  carbon dioxide enters through the stomataof the leaves, and the sun's energy is traped to make food, then oxygen given off into the air, sugsuggar or glucose exits the leaf into the plant


Tropism - growth movement a living organism has toward an enternal stimulus an example would be Diamond - leaf Willow

It can help since the tundra only has a minimum time of sun light they beable to get the sunlight to get there nutrients


Decomposers are very important in my ecosystem because they can enrich the soil to allow more plants to grow , if there weren't any decomposer there wouldn't be so much life in the tundra forest or not so many animal life

Foxes, caribou, any dead organism

Good information so far, but make sure it stays organized. It's getting a little hard to follow along.
