Organism Identification
The Brown Bear (URSUS arctos) is a bear that can be found mainly found in Asia, the Atlas Mountains of Africa, Europe, and North America, so basically all over the world. They mainly live in temperate forest, but this species of bears inhabits the most habitats of any other species of bear. In North America they are found in the northern temperate forest of Canada and Alaska. They also live in the temperate forest of Russia and all over the world. The Picture below is a drawing of a generic temperate forest.

The Picture below is a drawing of a generic temperate forest.
This Picture shows the generic habitat of the Brown Bear. It shows berries, honey, and fish foods that Brown Bears eat. There are birds, bees, a dear and fish all in this picture. There is also a small stream/river going through the forest. This pic shows many things a temperate forest consist of.
Synthesis
Brown Bears use Cellular respiration and the equation is C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy. These molecules are all organic.
Brown Bears are general organisms and things that they make inside of their bodies are blood, mucus, and male organisms produce sperm to reproduce.
Regulation
A brown bear is eukaryotic organism because it is an animal and all animal cells are eukaryotic. It is also a eukaryote because its cells consist of a nucleus. Another reason it's a eukaryote is because its organells are wrapped in a membrane.
There are many factors in the environment that can negatively impact brown bears that are both biotic and abiotic. Biotic factors that negatively affect are things like deforestation which is the cutting down of forest in parts of the world. This destroys Bear's habitats killing them off. Also hunters kill brown bears which is also biotic. Abiotic factors are things like temperature and water pH levels and things in water that may kill off Brown Bears because of unhealthy water or even water pollution.

Transport
Osmosis is the diffusion of water. It is the spontaneous net movement of solvent (water) molecules through a semi-permeable membrane (a living cell) into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. The solvent is typically water but can be other liquids and even gases. Osmosis occurs in brown bears to transport wasteful substances out of the cell and it keeps the cell healthy.

Diffusion is movement from higher concentration to lower concentration. It refers to the process by which molecules intermingle as a result of their kinetic energy of random motion. When there is equal amount of space between the molecules in diffusion its called an equilibrium. Diffusion occurs in brown bears because it exchanges toxic gases with life-sustaining gases.

Reproduction
Response
The Brown Brown Bear has adaptions from the short faced bear. Then it was the spectacled bear. Then that adapted into the Asiatic bear. That evolved in to the American Black bear. The short faced bear is now extinct. This is how bears have adapted to their environment. The benefit of these adaptions are for a Brown Bear can blend in with its environment to protect it self in another way than being not so violent. Just like a polar bear adapted to its environment by having white fur which is fit for the strong artic weather.

Organism Interaction
The Brown Bear is in the Animalia (animal) kingdom. It's in the animal kingdom because its a mammal a type of animal its a eukaryote, a multi-cellular organism, its heterotrophic, lacks a cell wall, and digest food inn an internal chamber. All of these are characteristics of an animal and the brown bear.
Biotic Factors: Trees, Grass, Mosses, Foxes, Deer, Mushrooms, Rabbits,
Abiotic Factors: Rocks, Soil, Streams, Rivers, tributaries, Weather
Modern Human behavior can affect the Brown Bear in many ways. One way is that brown bears and bears in general get attracted to human-created food sources and it draws them to the food and if they encounter the human most likely the bear will get killed. Also relocation of the animals which doesn't solve the problem for the encounters with human environment and it made lead to over-population and competition for resources when bears are located to other bear's and animal's habitats. People also hunt bears. Humans may think bears are trying to attack them, but they aren't so people get scared and in defense hurt and in some cases kill bears, These are all ways modern human behavior affects brown bears.
The brown bear can engage in the 3 types of symbiotic relationships. Brown bears can take part in parasitism by having a ticks or parasitic lice on them and the tick is getting blood from the bear and the bear gets harmed by losing blood. In Mutualism the brown bear eats berries from berry producing plants. This gives the bear food to eat and it helps the berry plants by spreading them across the bears habitat because when they drop the seeds in their waste a new berry plant can grow. In commensalism Brown Bears prey on salmon which helps regulates salmon population. Also, when baby brown bears are in danger they can climb up a tree for protection which helps the bear but doesn't hurt or harm the tree.
Innate behaviors include when it's winter the hibernate and another is when they see danger females stand up on two legs and defend their. cubs .

Species Interaction
Brown Bears are at the top of the food chain in their environment. While brown bear population numbers are currently stable, they are considered a high priority in conservation. Given their dependence on large natural areas, brown bears are important management indicators for a number of other wildlife species. Brown bears also play important roles as predators who keep other animal populations in check. For example, they feed on salmon and this keeps the salmon population to its carrying capacity. Additionally, they act as seed dispersers, helping to sustain their own environment.
