Which of the following statements are NOT correct?

A. Mahogany, Ebony and Rosewood are main trees of the Tropical Wet Evergreen Forest.
B. Sal and Teak are major species of the Tropical Monsoon Forest.
C. Chestnut tree is known as 'axe-breaker' in Chaco region of Paraguay and southern Brazil.
D. Chinchona tree bark is used to manufacture chewing gum.
E. Tannin is found in the bark of hemlock, mangrove species and teak trees.

Choose the correct answer from the options given below:

Correct option is D

The following statements are NOT correct:

• C. Chestnut tree is known as 'axe-breaker' in Chaco region of Paraguay and southern Brazil: This is incorrect. The chestnut tree is not commonly referred to as 'axe-breaker' in the Chaco region. The axe-breaker tree is actually Cebil (Anadenanthera colubrina) found in South America, particularly in the Chaco region.

• D. Chinchona tree bark is used to manufacture chewing gum: This is also incorrect. Chinchona trees (more accurately Cinchona) are known for their bark containing quinine, which is used to treat malaria, not for manufacturing chewing gum. Chewing gum is typically made from gum trees like the chicle tree.

• E. Tannin is found in the bark of hemlock, mangrove species and teak trees: This is incorrect. While tannins are indeed found in various trees, the specific combination mentioned in this statement is wrong. Hemlock, mangrove species, and teak trees do contain tannins, but they are not primarily known for this feature. Tannin is more commonly associated with oak, chestnut, and other specific trees.

Information Booster:

1. Mahogany, Ebony, and Rosewood: These trees are typically found in tropical evergreen forests where there is a constant warm climate and high humidity.
2. Sal and Teak: These species are characteristic of tropical monsoon forests that experience seasonal rainfall and temperature fluctuations.
3. Axe-breaker: The Cebil tree is often referred to as axe-breaker in South America due to the hardness of its wood.
4. Cinchona bark: The bark of the Cinchona tree contains quinine, a substance historically used to treat malaria, not for chewing gum production.
5. Tannin: Tannins are found in various plants and trees, but oak and chestnut are more renowned for their tannin content than the species mentioned in the question.

Additional Knowledge: 

1. A. Mahogany, Ebony, and Rosewood are indeed main trees of the Tropical Wet Evergreen Forest. These trees are known for their dense and rich wood and thrive in tropical rainforests.

2. B. Sal and Teak are major species of the Tropical Monsoon Forest. Both Sal and Teak are found in tropical monsoon forests and are known for their economic importance.
