Answer 2

Explanation:

Tropical forest:

• Tropical forests are found near the equator extending up to the tropic of Cancer and tropic of Capricorn.
• Tropical forests are of three types -

1. Tropical rainforests
2. Tropical deciduous forests and
3. Tropical thorn forests.

• These forests have a temperature range of about 15-30°C.
• Each type is distinguished by its dominating flora and fauna, and the climate.

Tropical Rainforests:

• Tropical rainforests are found in a narrow strip along the equator, typically between 10 north and south of the equator.
• These are evergreen forests with a warm and humid climate throughout the year.
• They receive an average annual rainfall of more than 200 cm, which might exceed 1000 cm sometimes.
• Of all the rainforests of the world, the Amazon rainforest is the largest.
• Tropical rainforest are home to an enormous number of plant and animal species.
• Many species in these forests are yet to be discovered.
• Tropical rainforests have tall trees that grow to a height of 40 m or more.
• Various vines, creepers and epiphytes are found growing on the tree trunks.
• Such forests have a dense canopy that allows very little light to reach the forest floor.
• As a result, the forest floor is almost bare of plants.
• The understorey has seedlings of trees that gradually grow up to the canopy.
• Some tall trees may penetrate through the canopy to form a very thin layer above it.
• This layer is called the emergent layer.
• Cinchona which yields quinine, Swietenia which yields mahogany, ebony, rubber durian, strangler figs, pitcher plants, and a variety of orchids are some of the plants that are found in these forests.
• Difterent species of insects like butterflies and beetles, arachnids like spiders and ticks, worms,large snakes like pythons, anacondas and boa constrictors, a variety of tree frogs, colourful birds, and mammals like monkeys, sloths and jaguars live in these forests.
