Question

100 БАЛЛОВ порівняйте рослинність зони саван і вологих екваторіальних лісів

Answer 1

Ответ:

Блище до зони перемінно-вологих лісів сформувалися високотравні савани. Тут високий трав'янистий покрив, більше дерев, з-поміж яких –олійне дерево, пальма дум, слонова трава. ... Чим далі на північ і на південь, тим рослинність бідніша-це типова або суха савана. Дощу тут не буває півроку

Answer 2

Comparison of Vegetation in Savanna and Tropical Rainforests

The vegetation in the savanna and tropical rainforest zones differ significantly due to variations in climate, soil conditions, and other environmental factors. Let's compare the vegetation in these two regions in more detail:

Savanna Zone: Savannas are characterized by a combination of grasses and scattered trees. The vegetation in savannas is adapted to the hot and dry climate, with distinct wet and dry seasons. Some key features of savanna vegetation include:

1. Grasses: Grasses are the dominant plant species in savannas. They have deep roots that allow them to access water during the dry season. Examples of grass species found in savannas include Rhodes grass, star grass, and buffalo grass.

2. Scattered Trees: Savannas have scattered trees that are adapted to survive in the dry conditions. These trees are usually deciduous, meaning they shed their leaves during the dry season to conserve water. Acacia trees and baobab trees are common in savannas.

3. Fire Adaptation: Savanna vegetation has adapted to frequent fires that occur during the dry season. Some grasses have underground stems that allow them to regenerate quickly after a fire, while some tree species have thick bark that protects them from fire damage.

Tropical Rainforest Zone: Tropical rainforests are characterized by dense and diverse vegetation. They are found in regions near the equator with high rainfall throughout the year. Here are some key features of tropical rainforest vegetation:

1. Canopy Layer: Tropical rainforests have a dense canopy layer formed by tall trees that compete for sunlight. These trees have large, broad leaves to capture maximum sunlight. Examples of canopy trees include mahogany, kapok, and rubber trees.

2. Understory Layer: Below the canopy, there is an understory layer consisting of smaller trees, shrubs, and ferns. These plants adapt to low light conditions and often have large leaves to capture available light.

3. Epiphytes and Vines: Tropical rainforests are known for their abundance of epiphytes, which are plants that grow on other plants for support. Orchids, bromeliads, and ferns are common epiphytes. Vines, such as lianas, are also prevalent in rainforests.

4. Biodiversity: Tropical rainforests are home to a wide variety of plant species. The high humidity and stable temperatures provide ideal conditions for plant growth and support a rich diversity of plant life.

In summary, the vegetation in the savanna zone is characterized by grasses and scattered trees adapted to hot and dry conditions, while tropical rainforests have a dense canopy of tall trees, an understory layer, and a high diversity of plant species. These differences in vegetation are primarily influenced by variations in climate and environmental conditions.
