Arctic Ecosystem

Biotic factors:

  1. Polar bears
  2. Arctic foxes
  3. Seals
  4. Musk Oxen
  5. Caribou
  6. Arctic Hares

Abiotic factors:

  1. Around 21 million miles of ice and land
  2. Temps average at below 0 degrees in the winter and 35 degrees in the summer
  3. The arctic gets around 100 inches of precipitation per year, mostly snow fall
  4. Winter lasts about 9 months, where as summer lasts about 2 months

I got everything from here: http://classroom.synonym.com/abiotic-biotic-factors-polar-regions-15818.html

Step 3

carrying capacity is the limit of how many organisms an ecosystem can support, an ecosystem's carrying capacity is determined by limiting factors.

For example, the polar bear population could change depending on how many seals there are in the population, how fast the ice is melting and how many polar bears can actually get to the feeding grounds with their cubs in tow.

I got the graph from google

Step 4

Limiting factors are a set of factors that prevent a population from growing any larger then the ecosystem can support

Some examples for my selected ecosystem are: Low temperature, low food supply, extreme weather and very little vegetation

Arctic Foxes depend on Arctic Hares for food, and the hares depend on what little vegetation there is, so if the hares cannot find their food supply due to it being very small, then the hare population will decline and so will the fox population, all because there wasn't enough plants

Step 5

Producers: Arctic Willow, Lichen, The Bearberry and Caribou Moss

Consumers: Arctic hare(herbivore), Arctic Fox(omnivore), caribou(herbivore), Polar bears(carnivore), Snowy Owls(scavenger)

Each of the above consumers gets their energy from consuming another organism, however, the arctic hare and caribou get their energy from plants, the polar bear gets its energy from other previously living organisms, the snowy owl eats what the polar bear doesn't and the fox gets its energy from both meat and plants

Producers are vital to an ecosystem because they, and they alone can change the sun's radiant energy into the chemical energy that can can be used in an ecosystem

Step 6

Food webs are more realistic because in a food chain, it only shows one way matter flows through an ecosystem when a food web shows many different possibilities

If you remove the seaweed from the above food web, the squid population would decrease because they lost a source of food

Step 8

CO2+H2O=C6H12O6 is the chemical equation for photosynthesis

Water, carbon dioxide and sunlight are needed for photosynthesis to occur, and oxygen and glucose are created in the chloroplast, where the radiant energy from the sun is turned into chemical energy

If the world was to get warmer, then the ice would melt and the amount of water in the oceans would greatly increase, causing the land area to flood

looks great so far! be sure to include headlines for when you transition from step to step.
