Biotic things in the Arctic
More living things in the acrtic.
Abiotic things in the Arctic.
Water (almost ice.)
Very little rain.
The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment.
If the seal population (the polar bear's food) starts declining for some reason (less water, human destruction, etc), the polar bear population will start to decline since their food source the seals have declined, and the polar bears could go extinct.
Limiting factors and predator/prey relationships.
Limiting factors are things that prevent a population from growing any larger.
A specific predator/prey relationship in the arctic is the penguin and the fish. If the waters were frozen for even more of a longer time than it already is, the penguins wouldn't be able to get to their food in time and would probably make the little baby penguins they're taking care of die, lessening the penguin population.
Energy Roles are determined by how the organism gains energy and how it interacts with other living things in its ecosystem. The three main energy roels are: Producers, Consumers, and Decomposers.
Some examples of producers in the Arctic are:
Some examples of First-level consumers in the Arctic are:
Some examples of Second-level consumers in the Arctic are:
Some examples of Third-level consumers in the Arctic are:
Some examples of decomposers in the Arctic are:
Lichen (both decomposer and producer)
Each of the energy roles receive its energy from the organism it feeds on (producers- sun, consumer- other consumer or producer... depends, decomposers- dead organisms, wastes, etc...)
Producers are vital to any ecosystem because they give out the energy which consumers take in, which makes them the base of the food chain, web, etc....
Food chains and food webs of the arctic
Food webs are more realistic than food chains for my ecosystem because we just aren't talking about one single food chain with only one producer or consumer(s), we are talking about more than one prey/predator which could (now be shown) feed on more organisms, and shows even more possibilities
If, for example, I removed the arctic foxes' population, and since the arctic fox is a prey of the polar bear, competition between the polar bears for other prey will happen, and the polar bear population will decrease greatly. Another example is the lemmings; if the arctic fox is removed, the lemmings will start to overpopulate, which will lead to competition since there won't be enough food for all the overpopulated lemmings, and many lemmings will die of starvation (and other factors).
Trophic Levels and Energy Pyramids
Why we use a pyramid shape is because as an organism eats another organism, they receive only 10% of the energy from the organism, which makes the top less and less populated with the consumers, and it shows the amount of energy left, which gets less as you go up, and no other shape gets smaller as it goes up.
Producers are in the largest level at the base because they have the most energy since they get it completely from the sun and the fact that their numbers are so large. Top predator are in the smallest level because they get the least of the energy out of them all and their population is the least.
Chemical Equation for Photosynthesis:
(water)+(carbon dioxide)-->(glucose[or sugar])+(oxygen)
What is needed for photosynthesis are sunlight, carbon dioxide, and water. What is produced by photosynthesis is oxygen.
Tropism is a biological phenomenon, indicating growth or turning movement of a biological organism, usually a plant, in response to an environmental stimulus.
