A biome is different from an ecosystem. An ecosystem is the interaction of living and nonliving things in an environment. A biome is a specific geographic area notable for the species living there. A biome can be made up of many ecosystems. For example, an aquatic biome can contain ecosystems such as coral reefs and kelp forests. In our desert biome there are many ecosystems: we have salty lakes, pure rivers and creeks, salt beds, small forests, lush forests...in each ecosystem there are different populations of organisms. Biomes move as the climate changes. Ten thousand years ago, parts of North Africa were lush landscapes cut by flowing rivers. Hippopotamuses, giraffes, and crocodiles lived amid abundant trees. Gradually, the climate dried out. Today, this region is part of the Sahara Desert, the world's largest desert. Each biome has their own characteristic:
TUNDRA TAIGA TEMPERATE DECIDUOUS FOREST (Moderate temperatures/trees lose their leaves) forest SCRUB FOREST or CHAPARRAL GRASSLAND DESERT TROPICAL RAINFOREST TEMPERATE RAINFOREST OCEAN RIVERS and STREAMS If anyone tells you Earth is a boring place, slap them in the face and say "WAKE UP!"

Mrs. TaylorI love science! Everything about the world is interesting and never boring. I love to study plants, animals, insects, and people. My favorite subjects are my students who are the most unique organisms on the planet! Categories |
