What is a Biome?
A biome is a large area with similar flora, fauna, and
microorganisms. Most of us are familiar with the tropical
rainforests, tundra in the arctic regions,
and the evergreen trees in the coniferous forests.
Each of these large communities contain species that are adapted to its
varying conditions of water, heat, and soil. For instance, polar
bears thrive in the arctic while cactus plants have a thick skin to help
preserve water in the hot desert. To learn more about each of the

What is an Ecosystem?
Most of us are confused when it comes to the words ecosystem
and biome. What's the difference? There is a slight difference
between the two words. An ecosystem is much smaller than a biome.
Conversely, a biome can be thought of many similar ecosystems throughout
the world grouped together. An ecosystem can be as large as the Sahara
Desert, or as small as a puddle or vernal pool.
Ecosystems are dynamic interactions between plants, animals,
and microorganisms and their environment working together as a functional
unit. Ecosystems will fail if they do not remain in balance.
No community can carry more organisms than its food,
water, and shelter can accomodate. Food and
territory are often balanced by natural phenomena such as fire, disease,
and the number of predators. Each organism has its own niche, or
role, to play.
