ECOSYSTEMS
Scientists divide the earth into number of different
vegetation zones. The plant and animal life depend on a region’s
climate,
landscape, and latitude. Plants and animals have adapted to life in
these climates, often developing features to help them to survive. |
|
|
| Mediterranean:
hot, dry summers and cold, wet winters (plants and trees have adapted
to lack of water). |
|
 |
|

|
Mountains
Regions: the higher, the colder, with peaks often in snow. Trees
and plants grow on lower slopes only. Above the tree line, it is too
windy and clod for plants to survive. |
|
| Tropical
Grassland: hot climate divided into wet and dry season; between
tropical rain forests and hot dessert, called African savanna with
tall grasses and low trees and shrubs. |
|
 |
|
 |
|
Dry
Grassland: hot, dry summers and very cold winters (often used
for wheat or cattle). |
|
| Hot
Desert: hottest, driest places on Earth; heat during a day to
often below the freezing temperatures at night. In some deserts, years
pass with no rain. Deserts have sandy soil that supports. |
|
 |
|
 |
|
Tropical
Rain Forest: hot and wet all year round, ideal for lush, green
forests around equator. Rain forests may contain 50,000 different
types of trees, and millions of plants and animals. |
