The Tundra Ecosystem
Tundra Ecosystem is very cold. It is covered in snow.
Biotic and Abiotic Factors
Strong winds,poor soil,short summer days,little rainfall,mountains
-the number of people, other living organisms, or crops that a region can support without environmental degradation
-in order to survive you need: food, water, shelter, space
The populations of the penguins decreases when warming starts to happen in their shelter.
-are things that prevent a population from growing any larger
-example of limiting factors: disease, temperature, etc.
Penguins are preys to many animals for example leopard seals are one of them.
primary consumer-herbivore: pikas
secondary consumer-carnivore: arctic wolf
tertiary consumer-omnivore: arctic polar bear
decomposer -break down organisms to make nutrients :fungi
scavenger-animals that eat off of animals that's already dead: snowy owl
Producers get their energy from the sun, consumers get their energy from producers, and decomposers get their energy from dead organisms.
Producers are very vital to the ecosystem because it is the only organism that can make its own food to provide for other organisms.
Food Chains vs. Food Webs
Food webs are more realistic to our ecosystem than food chains because the organism has more than one predator.
By moving the arctic wolf the arctic hare population would increase then the producers would eventually run out and every organism would starve.
Trophic Levels and Energy Pyramids
The reason why its a triangle is because it shows how much energy the organism has as it goes up the pyramid.
Producers are on the bottom because it has the most energy from the sun.
