Plants
* Trees: Coniferous trees like pines, firs, and spruces dominate higher elevations, giving way to deciduous trees like oaks and maples at lower altitudes.
* Shrubs: Heather, rhododendrons, and mountain laurel are common examples.
* Grasses: Alpine meadows are home to various grasses adapted to harsh conditions.
* Wildflowers: Mountains are known for their diverse wildflowers, with species blooming at different elevations and seasons.
* Mosses and Lichens: These organisms thrive on rocks and tree trunks, often forming carpets of green or colorful patterns.
Animals
* Mammals: Deer, elk, bears, mountain goats, marmots, squirrels, and various rodents inhabit mountains.
* Birds: Hawks, eagles, owls, songbirds, and migratory birds are common sights.
* Reptiles and Amphibians: Lizards, snakes, salamanders, and frogs are found at lower elevations, with some species adapted to colder, higher altitudes.
* Insects: Mountains are home to a wide array of insects, including butterflies, beetles, ants, and bees.
* Fish: Trout and other fish inhabit the streams and lakes found in mountainous regions.
Microorganisms
* Bacteria: Bacteria play a crucial role in decomposition and nutrient cycling within mountain ecosystems.
* Fungi: Mushrooms, molds, and yeasts decompose organic matter and form symbiotic relationships with plants.
* Viruses: Viruses are present in mountain ecosystems and can affect the health of plants and animals.
Other Interactions
* Competition: Different species compete for resources such as food, water, and sunlight.
* Predation: Predators like wolves, bears, and hawks hunt prey species.
* Parasitism: Parasites like ticks and fleas feed on other organisms, often harming their hosts.
* Mutualism: Some species benefit from a mutually beneficial relationship, such as bees pollinating flowers.
Remember that the specific biotic factors present on a mountain will vary depending on its location, elevation, and climate.
