Biotic and Aboitic

Abiotic: chunks of ice(broken), currents of water that goes down to 0'C, 90% of the sunlight is absorbed into the ocean warming up.

Biotic: diatoms(plankton),protist(plankton),dinoflagellates(plankton), algae, humpback whales, polar bears, emperor penguins, seals, walrus, and killer whales.

Carrying Capacity
-the availability of habitat components and the numbers of animals the habitat can support

Some resources that are mostly needed to survive contain most of: food, water, shelter, and camouflage

Limiting Factors and Prey/Predator relationships

Some limiting factors include:1. ExtremelyLow Temperature

2. Limited Supply of food
3. Limited means of transportation
4. Low vegetation
5. Slow pace of life
6. Exteme Weather


Energy Roles

Producers: Lichen and Grass

Consumers/Herbivores: Arctic Hares, Lemmings, Caribou

Consumer/Carnivore: Polar Bear, Brown Bear, Arctic Fox, Black Wolf

Consumer/Omnivore: Brown Bear

Decomposer: Reindeer Moss

Scavengers: Canids, Wolverines, Birds, Ground Beetles

The producers get their energy from the sun, then the herbivores get their energy from plants, next the carnivores eat the herbivores, scavengers eat the dead reamins of animals, then decomposers break down the dead animals left.

The producers take the sun's energy using photosynthesis and when producing that energy they die due to herbivores and the energy goes to the herbivore.

Food chains ad Food webs

Food webs can consist of many food chains and what makes it realistic is that it list of all animals that die to its predator or if the predator is killed by another.

Trophic Levels and Energy Pyramids

The reason of using a pyramid instead of a cube or cylinder is that the pyramid shows the amount of energy left for the animals since only 10% of the energy is transferred to another organism and the rest is lost by life process/heat the animal will grow weaker till eventually is dead and decomposes.

The producers are the biggest level of the rest because of the amount of energy that it gets from the sun. While others can't produce their own food, plants can take the energy from the sun and use it to their use till they are eaten.


CO2  +  H2O-------> C6H12O6  +  O6


In the arctic you have...

Geotropism- response to gravity

Hydrotropism- response to water

Phototropism- response to sunlight

thigmotropism- a way a plant grows by touch

The tropisms listed to help survive is to have their energy produced so when a herbivore walks by and eats it then 10% is transferred to the herbivore

The Role of Decomposers

the reason to have decomposers is to have some animals breaking down dead plants and animals to the soil and leave good nutrients for plants that grow there. If there are no decomposers then all the dead animals and plants will decay and rot giving off a bad smell and plants won't be able to grow as much as plants that recieve nutrients from the ground

I think it is a great thing that you were so specific but remember to site your source

i recommend that you add pictures before you say your abiotic
