List the features of tropical evergreen forests and tropical deciduous forests
Answers
Tropical evergreen forests are usually present in areas receiving more than 234 cm of rainfall and having a monthly mean temperature of 18 °C or higher in the coldest months . Tropical evergreen forests are dense, multi-layered, and provide home to many types of plants and animals. These forest are concentrated in the areas receiving heavy rainfall . They are very dense and as such the sunlight does not reach the ground. Numerous species of trees are found in these forests which shed their leaves at different times of the year.As a result these forests always appear green and are known as evergreen forests. These forests are found in the Andaman and Nicobar Islands, along the slopes of Western Ghats and parts of Northeastern states of Assam, West Bengal and Odisha. These areas are hot and humid climate with shorter duration of dry season. The important trees of these forests are rosewood, ebony and mahogany.
Tropical deciduous forests are present in regions with heavy rainfall for part of the year followed by a dry season. These forests are dense and lush during the wet summers, but become a dry landscape during the dry winters when most trees shed their leaves. By shedding their leaves they conserve water during dry periods. Bare trees open up the canopy layer, enabling sunlight to reach ground level and facilitate the growth of thick underbrush. Trees use underground water during the dry seasons. Tropical deciduous forests occur in drier areas north and south of the tropical rainforest belt, south or north of the subtropical deserts. The most diverse dry forests in the world occur in southern Mexico and in the Bolivian lowlands. The dry forests of the Pacific Coast of northwestern South America provides a wealth of unique species due to their dry climate.
The canopy layer of tropical rain forests is said to be a standout among the most differing environments on the planet. It towers over the forest floor, making a roof that enables next to no light to achieve the ground.
Plants which can be found grown on the canopy:
Vines:
In excess of 2,500 vine species are known to exist inside the world's tropical forests. Vines dependably utilize existing vegetation for help as they grow up toward the canopy.
Bryophytes:
Bryophytes are nonvascular plants, implying that they don't have xylem and phloem. (Interestingly, the "strings" in a celery stalk are groups of vascular tissue that help supplements and water through the plant.)
Bromeliads:
Bromeliads develop in incredible abundance in the rain forests. There are more than 2,700 species known. These plants can assimilate every one of their supplements and water from the encompassing air.
