Which type of biome is characterized by warm to hot summers, cold winters, seasonal precipitation, and very fertile soils? | Temperate Grasslands (think of Iowa), |
Which type of biome do we live in? | Temperate forest (a.k.a. - Temperate deciduous forest*), |
This biome has moderate temperatures (0°C - 20°C or 32°F - 75°F) with a lot of rainfall (200-300cm or 78-120in).
This biome has permanently frozen ground (permafrost). The temperature ranges from an average of -34° C (-30° F) to 12°C (54° F). The precipitation is low 15 to 25 cm (6 to 10 inches), which is why it is sometimes considered a cold desert.
This tropical grassland has temperatures that range from 20°C (68°F) to 30°C (86°F). Most of the 76-127cm (30-50in) of rain falls during the wet season with less than 10cm (4in) of rain falling during the dry season.
Due to the climate, there is a large amount of biodiversity in living organisms here. The ground is permanently frozen, called the permafrost layer. Sometimes called the cold desert, characterized by COLD winters, and very short summers. Too little rainfall and low temperatures mean that only small plants grow here.
For example, they consider different kinds of forests to be different biomes. Tropicalrain forests that are warm and wet year-round are one biome. Temperate deciduousforests—those that have cold winters, warm summers, and are dominated by trees that lose their leaves—are a different biome. Taigaforests, which are in cold regions and are dominated by cone-bearing firs and spruces, are yet another biome.
There are more than a dozen ways to classify biomes. Climatologists, botanists, ecologists, biologists, and anthropologists have different criteria for deciding what constitutes a biome. One of the simplest classification systems has only two biomes: terrestrial (land) and aquatic (water). One of the most complex has more than a dozen.
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 aquaticbiome can contain ecosystems such as coral reefs and kelp forests.
However, scientists disagree on how many biomes exist. Some count six (forest, grassland, freshwater, marine, desert, and tundra), others eight (separating two types of forests and adding tropical savannah), and still others are more specific and count as many as 11 biomes. Use these resources to teach middle school students about biomes around the world.
Biomes move as the climatechanges. Ten thousand years ago, parts of North Africa were lushlandscapes cut by flowing rivers. Hippopotamuses, giraffes, and crocodiles lived amidabundanttrees. Gradually, the climate dried out. Today, this region is part of the Sahara Desert, the world's largest desert.
A biome is an area of the planet that can be classified according to the plants and animals that live in it

biomes: communities of plants and animals that are defined geographically and climatically.

Biomes are regions of Earth that have similar climates and other abio tic. abiotic: physical factors or conditions that influence plant and animal life.
A simple way to organize biomes is by their climate (temperature and precipitation). A scientist by the name of Robert Harding Whittaker was the first to propose the scheme pictured to the left. This is one type of classification scheme that you will see in this lab. Carefully examine the graphic, left, especially note the temperature and precipitation scales. The temperature scale, given in degrees Celsius, is the average temperature for a typical year. The precipitation scale, in centimeters per year, is the average of the total precipitation for a typical year. For example, Phoenix, Arizona, a subtropical desert, has an average temperature of 29.2˚ C (84.6 ˚F) and receives an average of 21 cm (8.3 in) of rain per year. Click on the image for a larger view. Consider the advantages of organizing biome types in this manner.

abiotic: physical factors or conditions that influence plant and animal life. (non-living) factors such as elevation, humidity, and soil type. No matter where they occur on the planet, biomes have similar types of vegetation and animal life, or ecological communities. In this lab, you will study the major types of terrestrial (land) ...
