4. What is Commensalism in Yellowstone National Park?

Commensalism in Yellowstone National Park refers to a symbiotic relationship between two organisms where one benefits and the other is unaffected. This type of relationship can be observed in various interactions within the park’s ecosystem.

One example of commensalism in Yellowstone is the relationship between bison and birds. Bison create disturbances in the soil while grazing, which exposes insects and other small organisms. Birds, such as the mountain bluebird, take advantage of this by feeding on the exposed insects without causing any harm to the bison. The bison are unaffected by the presence of the birds and continue with their grazing activities.

Another example of commensalism is the relationship between elk and wolves. Wolves are apex predators in Yellowstone and often prey on elk. However, when wolves make a kill, scavengers such as ravens and bald eagles gather to feed on the carcass. Elk, on the other hand, benefit from this relationship as they can detect the presence of scavengers and use it as an early warning system to avoid potential predation.

Commensalism plays an important role in maintaining the balance and biodiversity of Yellowstone National Park.

5. What is Parasitism in Yellowstone National Park?

Parasitism in Yellowstone National Park refers to a symbiotic relationship between two organisms where one organism, known as the parasite, benefits at the expense of the other organism, known as the host.
