Hi! My name is John and I am a ranger here at Yellowstone. Today I wanted to talk about populations.
Grizzly bears are one population that is important here in Yellowstone. Their population has fluctuated over time due to many factors.
For example, if there were too many bears, there would be no fish or berries left to eat.
The carrying capacity of an environment is the maximum population it can support.
Limiting Reactants include natural disasters, like forest fires, human interactions with bears, food availability, and competition with other species.
Some factors affect the population of grizzly bear species here. They are known as limiting reactants.
For example, we have lots of campers here at Yellowstone. Sometimes they leave trash, which the bears eat. This can lead to a decrease in the Grizzly population because of sicknesses and injuries they can get from the foods and packaging.
If the trout population here increases, the bear population also increases because of the increased food supply.
