What exactly is an ecosystem? How is it different from a biome? Here is one way to think about it:
- Individual plants or animals living together are called a population.
- Several populations are called a community.
- Several communities form an ecosystem.
- Ecosystems sharing the same climate make up a biome.
- All earth's biomes form the biosphere.
What these groups all have in common is interdependence. Living things do not exist in isolation. They constantly interact with each other and with their environment and are dependent upon each other for survival.
The parts that make up an ecosystem are plants, animals, and the environment in which they live, including soil, air, water, sunlight, minerals, and nutrients. All of these parts interact in energy and nutrient cycles.
Enemies to ecosystems are human activity and pollution. How we interact with an ecosystem can have impact thousands of miles away. For example, monarch butterflies that live across the United States migrate to parts of California and Mexico during the winter. In California, many sites historically frequented by monarchs have been destroyed by human development. Destroying habitat in California could potentially bring about monarch butterfly decline throughout North America.

The following are places to go (some real and some virtual) to find out about ecosystems.
This flat, white, barren destination is very unique and shouldn't be overlooked. If you can't actually visit the flats, then learn about it from the internet.
Visit this virtual forest, find the hidden animals, and click on them for more information.
Visit the Great Salt Lake. Our state's famous lake is a terminal lake. What is that? How much saltier is it than the ocean? Are there any fish in the Great Salt Lake? Why does it sometimes smell so bad.
The Scott M. Matheson Wetlands Preserve is an oasis in the desert - a stark contrast to the surrounding redrock cliffs and arid desert.
