What is an ecology?
Ecology is the study of how organisms interact with their environment. An organism's environment includes nonliving, or abiotic, features such as temperature, sunligh, rain, rocks, and ponds. An organisms environment also includes biotic features, which is other living things.
Ecologists often focus on questions at one of three levels:
Ecologists often focus on questions at one of three levels:
- A population: is a group of individuals of a single species that lives in a specific area.
- A community: consists of all the organisms that live in a given area.
- An ecosystem: consists of all the organisms that live within a given are and all the abiotic features of their environment.
Nature fearures and ecosystems in shenandoah national park
Shenandoah National Park includes 300 square miles of the Blue Ridge Mountains in the southern Appalachians. The park rises above the Virginia Piedmont to its east and the Shenandoah Valley to its west. Two peaks, Stony Man and Hawksbill, exceed 4,000 feet. The range of elevation, slopes and aspects, rocks and soils, precipitation, and latitude create a mix of habitats. Tens of thousands of living creatures make their homes in the park, from black bear resting beneath rock overhangs, to tiny aquatic insects darting through cool mountain streams. The park's many worlds are fascinating to explore. Most of Shenandoah's landscape is forested. In the process of photosynthesis, converting light, water, and minerals into foods, green plants give off oxygen. From a distance this air-born water creates a faint haze giving the Blue Ridge its name. In recent years, the haze has taken on other ingredients, introduced by humans. Air is among the resources the staff at Shenandoah National Park is duty bound to protect. Hardwood forests dominate the park. The forests are the result of many disturbances, some measured in geologic time, others in minutes. Remnants of boreal forests remind us that continental glaciers came near. Strands of barbed wire embedded in trunks mark the edges of former pastures. Uprooted trees show the path Tropical Storm Fran made in 1996. Shenandoah national park is considered a taiga biome. The taiga is the biome of the needleleaf (coniferous) forest. It could also be considered as a temperate deciduous forest. Fire is needed for some plants to grow.
