Mission:Biomes

What is Biome?
Biome
-are large community units that comprise a distinctive natural ecosystem in a particular region.
-classified based on the most type of vegetation.
Biosphere
-Several collection of biomes
-Consist of water component, land component and atmosphere component
Tropical Biomes
1. Tropical rainforest
- characterized by year-round warm temperature 
- rainfall determines the kind of vegetation growing in the area
- the most complex biome
-  high rate of precipitation
Fig. 1. Plants and animals found in Tropical Rainforest.
The tropical rain forest can be found in three major geographical areas around the world:
     Central America in the Amazon river basin.
Africa - Zaire basin, with a small area in West Africa; also eastern Madagascar.
 Indo-Malaysia - west coast of India, Assam, Southeast Asia, New Guinea and Queensland, Australia.
2. Savanna
- is a rolling grassland scattered with shrubs and isolated trees, which can be found between a tropical rainforest and desert biome.
-Not enough rain falls on a savanna to support forests.
-also known as tropical grasslands.

Seasons in Savanna
-Very long dry season
-Very cold winter
Temperate Biomes
1. Temperate rainforest
- Characterized by harsh and long winters with heavy snowfall and occasional warm summers
- Dominated by a few species of tall tees like cone-bearers (spruce, pine and hemlock)

2. Chaparral
-Characterized by a large number of shrubs with evergreen leaves.
-Long rainy winters and very hot summers

3. Tundra
-   Located at high latitudes
-    Covered with ice
-  The climate is extremely cold with little daylight very little precipitation because of permafrost
-  Trees don’t grow in tundra
4. Taiga
-Dominated by conifers which includes pines firs and spruce
-Snow is the form of precipitation
-Trees can withstand to the its very cold climate

5. Desert
-Extremely hot daytime temperature but have cold nights
-Have no perennial vegetation
-Many of the animals are nocturnal

Aquatic Biomes
1. Marine Biome
-The marine biome is the biggest biome in the world! It covers about 70% of the earth
-includes five main oceans: the Pacific, Atlantic, Indian, Arctic, and Southern
2. Fresh water biome
-include lakes, ponds, rivers, and streams
- Plants and algae are important to freshwater biomes
