Keywords:

  • Climate
  • Soil
  • Rainforest
  • Precipitation
  • Distribution of tropical rainforest


Answer:

Biomes are plant and animal community that covers a large geographical area.
Boundaries of the different biomes are determined mainly by climate. Climatic factors include rainfall, temperature, humidity, and soil conditions.
The following are major biomes of the world:

  • Forest Biome
  • Grassland Biome
  • Desert Biome
  • Tundra Biome
The Forest biome can be further classified into four main types:

  • Tropical Rainforest
  • Deciduous forest
  • Temperate forest or Mediterranean forest
  • Coniferous or Taiga or Boreal forest

Tropical Rain forest:
The tropical rainforest is comprised of 6 % of the earth's land surface and is distributed between 10 degrees north and 10 degrees south latitudes.
Distribution of tropical rain forests in the world:


  • In South America:
    • Brazil
    • Venezuela
    • Colombia
    • Peru
  • In Africa:
    • Congo
    • Angola
    • Zambia
    • Uganda
    • Madagascar
  • New Guinea
  • Australia
  • Indonesia
  • India
  • Myanmar
  • Sri Lanka

The following are the main characteristics of the tropical rainforest biome:

  • Climate:
    • As per Koeppen's classification, it is categorized as "Af".
  • Temperature
    • 20 to 25 degrees centigrade; temperature is evenly distributed.
  • Precipitation:
    • Highest on the earth
  • Soils: 
    • Acidic due to vegetation leaf
    • Poor nutrients in the upper layer of soil due to high rainfall leached nutrients to the lower layer of the soil profile
    • Although organic material such as plant residue and dead animals are produced in large quantity, however, due to high temperature and high precipitation decomposition rate is also very fast.  Hence, humus content is poor in soil.
  • Flora and fauna:.
    • Multi-layered canopy tall and large tree.
    • Some trees are 120 feet tall
    • Colorful full birds, insects, and animals exist
