Consider the following trees: 1. Jackfruit (Artocarpus heterophyllus) 2. Mahua (Madhuca indica) 3. Teak (Tectona grandis) How many of the above are deciduous trees?

Deciduous forests are dominated by trees that lose their leaves seasonally and are widespread in India, often called monsoon forests. They thrive in regions with 70-200 cm of rainfall and are divided into moist and dry types based on water availability.

Moist Deciduous Forests: These are prominent in areas with 100-200 cm rainfall, including the northeastern states, Himalayan foothills, eastern slopes of the Western Ghats, and Odisha. Key species include Teak (Tectona grandis), sal, shisham, hurra, mahua (Madhuca indica), amla, semul, kusum, and sandalwood.

Dry Deciduous Forests: Found where rainfall is 70-100 cm, they transition to moist deciduous forests in wetter areas and thorn forests in drier areas. These forests are present in rainier parts of the Peninsula and the plains of Uttar Pradesh and Bihar. In high rainfall zones of the Peninsular plateau and northern Indian plain, they feature a parkland landscape with teak and other trees interspersed with grass. Trees shed leaves completely during the dry season.

Jackfruit (Artocarpus heterophyllus) is an evergreen tree native to tropical Asia, known for its large fruits and durable wood. It's the largest tree-borne fruit globally.

Therefore, Mahua and Teak are deciduous trees, while Jackfruit is an evergreen tree.

Hence, only two trees are deciduous.
